11.17 17th December, 2015
  - The thumbnail size slider can now be made to preserve the currently set 
  aspect ratio, by adding the "preserve" keyword to the Args 
  field when editing the field's underlying command. 
  
 - The thumbnail size slider, and Show THUMBNAILSIZE by 
  default, now affect hidden folder tabs as well as the visible ones. 
  
 - The Go command has a new TOFRONT 
  argument which makes the lister the active window and brings it to 
  the front. This can be useful if you need to send Opus a single-line command 
  from an external program and want to both change folders and activate the 
  window. 
  
 - Set COLUMNSTOGGLE=columnlist,insert now inserts nearest 
  where you right-clicked, instead of always inserting to the left of the column 
  you clicked on. 
  
 - Fixed an error uploading to some SSH SFTP sites. 
  
 - The combination of Single Click and Full Row Select modes now interprets 
  clicks anywhere on the line as a double-click, instead of only on the name 
  part. (Unless Preferences / Miscellaneous / Advanced: single_click_rename 
  is on.) 
  
 - Fixed scrollbars and full row selection rectangles not updating to account 
  for bold labels in auto-sized columns when changing folders. 
  
 - Windows 10: Open With > Choose Default Program now lets you set a 
  default program again, not just select which program is used to open the file 
  once. 
  
 - Breadcrumbs path field now respects the Select previous folder when 
  going up Preferences setting by default. The selectprevious 
  and noselectprevious args can be used to override 
  this. 
  
 - The Drives List drop-down will now take you to the root of the 
  drive if you select the drive you are already on. (Previously, it did nothing, 
  even when the curdir argument was not specified.). When the 
  curdir argument is used this must be enabled by adding the 
  rootmode argument as well. The same change also applies to 
  the Go DRIVEBUTTONS command when CURDIR 
  argument is used. 
  
 - Metadata panel defaults to the current folder when you add cover art. 
  (Since the cover art is usually already in the same folder as the music.) 
  
 - Metadata panel would show coverart unghosted if you selected one file, 
  then ctrl-selected another with different art. Both covers should be ghosted 
  unless changed or in both files. 
  
 - Fixed Windows Search results from the previous query coming into the 
  results collection if you changed the query while the previous one was about 
  to return results. 
  
 - Fixed libraries pointing at network paths loading slowly if localized 
  paths were enabled. 
  
 - Fix for status bar which could appear over some lister elements if it was 
  turned off and you switched to dual display. 
  
 - Tooltips in some list controls (mainly in Preferences, not the file 
  display) could show text for the item above the mouse pointer in some 
  situations. 
  
 - Fixed cosmetic issue with Thumbnails mode where tiny thumbnails (or huge 
  fonts) could cause labels to draw on top of each other in extreme cases. 
  
 - Fixed cosmetic issue with Tiles mode and the Details mode Thumbnail 
  column. The case of CD cover thumbnails could grow larger than the cover art 
  inside it. 
  
 - Fix for the script log not showing all script output when scripts 
  generated a huge volume of messages at once. 
  
 - Fixed memory leak when using script columns. 
  
 - Fixed memory leak each time a Rename or Column script was called for a 
  file. 
  
 - Fixed scripting doubleClickData.mouse always showing 
  "none" outside of Details and Power modes. 
  
 - Fix for script columns not working for all items in folders with around 
  10,000 items or more. 
  
 - Fix for crash which could occur with some script code. e.g. "Set x = 
  Nothing, DOpus.Output x" 
  
 - Windows 10: The folder tree no longer shows duplicate copies of removable 
  drives under both Desktop and This PC branches (sometimes reported as empty 
  drives being shown). 
  
 - AudioTags plugin now handles incorrect FLAC files with ID3 data before the 
  "fLaC" header by skipping over it. 
  
 - Fixed a number of issues with high DPI displays.
   - Static context menu items that have localized strings for labels now work 
  if they use an environment variable (e.g. @%CommonProgramFiles%\...) to load a 
  string from a DLL. 
  
 - Copy MAKELINK AS now guards against creating a shortcut 
  on top of the file being pointed to. 
  
 - Fixed Create Multiple Folders checkbox not always redrawing 
  immediately if toggled via the keyboard. 
  
 - Clicking the Sync panel's source/dest swap button now also swaps the lock 
  states of the two path fields. 
  
 - The Find and Dupes panels now automatically unlock their folder lists when 
  the lists are modified. 
  
 - Fixed crash when changing Find In folder via the browse dialog in specific 
  circumstances. Fixed the new destination tab opened for Find Results being 
  made the source if it triggered dual display opening and the global option to 
  open the dual display as source was on. 
  
 - Renaming the case of things inside Rar and 7z archives now works. 
  
 - Adding files from collections (including search results) to archives is 
  now faster for Zip and now possible for plugin formats (7z, RAR, etc.). 
  
 - If you launch a folder that is already open in the destination side of a 
  dual-display lister, that side will now be made the source, so you can 
  immediately use the folder via the keyboard. 
  
 - Fixed copied folders gaining the A attribute when preserving attributes, 
  if NTFS ADS metadata for them was also copied. 
  
 - Fixed metadata panel only allowing the mouse wheel to increase, not 
  decrease, the MP3 year tag if it was empty before clicking on it. 
  
 - If you ran the Duplicate Finder with nothing defined for the output 
  collection, the Select button did not work. 
  
 - Opus now attempts to detect when third-party DLLs incorrectly call the 
  WSACleanup() function, which can cause Opus FTP to stop working. If an 
  incorrect call is detected Opus will block it and inform you of the faulty 
  DLL's name. 
  
 - If Opus detects it is running elevated on a machine with UAC enabled, it 
  now displays "ADMINISTRATOR" in the titlebar so it is easy to detect. It also 
  adds warnings beside Preferences options related to things which only work 
  when Opus is run normally, like Explorer Replacement and Desktop Double-Click. 
  (See http://www.gpsoft.com.au/DScripts/redirect.asp?page=uacfaq 
  for more information. Generally, you should use the built-in UAC support and 
  Administrator Mode rather than run the whole program elevated.) 
  
 - SSH - Updated putty to 0.66 (minor changes only). 
  
 - Windows 10: Double-clicks on PDF files now work on a vanilla Windows 10 
  machine. (May also fix double-click issues with some other file types that 
  don't have a file type class registered.) 
  
 - Fix for drag & drop not working from Calibre to Opus. 
  
 - Fix for crash which could happen when holding down a hotkey for several 
  seconds, triggering folder read/refresh, with either scripts diverting the 
  read to a different folder or a folder that takes a long time to read. 
  
 - Fixed problem that could cause TortoiseSVN status icons to not update 
  after a commit.
   - The list under Preferences / Display / Fields now only draws items in 
  custom font styles/colors if they are enabled. 
  
 - Select Folder dialog (e.g. from Find panel's browse button) no longer 
  selects the special Local Harddrives item when it isn't supposed to, and now 
  does select it when it is supposed to. 
  
 - Windows 10 and 8.1: Select Folder dialog (e.g. from Find panel's browse 
  button) now filters the This PC (aka My Computer) branch to exclude things 
  which are not drive roots, removing the profile folder clutter Windows has put 
  there. 
  
 - The "Allow file selection when clicking..." mouse options are now more 
  consistent with their descriptions, between Details/Power and other modes, and 
  with how they handle selection vs deselection. 
  
 - Fix for lister not coming to the front if "Allow file selection when 
  clicking to switch source/destination state" was turned off and the lister was 
  activated by clicking on a file outside of Details and Power modes. 
  
 - Improved UAC elevation "ADMINISTRATOR" warnings added in 11.16.3 to 
  exclude built-in admin account if not subject to UAC. 
  
 - Fixed a crash if you closed the Customize dialog when you had a context 
  menu's submenu displayed.
   - Fixed breadcrumbs path field sometimes showing the wrong icon for the 
  current folder when editing the path, and in the drop-down list. 
  
 - Fixed path field drop-downs ending up with multiple items for the same 
  folder if the Recent list was disabled. 
  
 - Fixed Breadcrumbs and Recent path field drop-downs using the per-lister 
  History limit to trim the Recent list, if they are displaying it. 
  
 - Fixed bug which stopped the FTP Quick Connect function from working when 
  selecting a site from the dropdown list 
  
 - Added MDTM/MFMT support for setting folder dates in FTP transfers
