TreeComp versions

v4.0 [Dec 13, 2011]
On November 9th 2010 I released TreeComp 4.0 b21. It fixes an "index out of bounds" problem introduced with version 4.0 b20 (thanks again cjl/CLASystems!).
On November 10th 2010 I released TreeComp 4.0 b22. It fixes weird behavior in the "Select directories" dialog.
On November 30th 2010 I released TreeComp 4.0 b23. It accepts a single folder on the command line and disables controls while scanning and copying as requested by Guido Eisenbeis. Added autocompletion to the "Select Directories" dialog.
On December 7th 2010 I released TreeComp 4.0 b24. It fixes a problem with tildes ('~') in the directory names and disables the toolbars while scanning, thanks again Guido Eisenbeis!
On March 15th 2011 I released TreeComp 4.0 b25. It improves interrupts and disables the GUI completely while scanning or copying (thanks Peter van de Ven!). I also addressed a rare problem with the location of the TreeComp window after minimize and restore while copying (thanks again Peter van de Ven). Next, I fixed a bug to include the offset from UTC to show the correct date for files (thanks Peter Remeijer). Finally, I added a prefix option that also allows to move files from one folder to another using "Rename or Move" or "Prefix" from the context menu.
On March 30th 2011 I released TreeComp 4.0 b26. A fix was added for the tool buttons "Copy more recent files from to " and "Copy more recent files from to ": when unmatching files (e.g. left only) were selected they were erroneously copied, allow to move files from TreeComp to e.g. Windows Explorer using drag and drop by pressing the Shift key, use asynchronous drag and drop to keep TreeComp responsive, correctly populate list of files to drop (3 times thanks to Nicolas SPORN). Enclosed all arguments containing spaces in double quotes to the File Comparison Utility and the Editor, not only existing files or directories (Thanks Bob Brand). Fixed a bug where File Comparison Utility (e.g. WinDiff) or the Editor was opened an infinite number of times (happened when multiple items were selected).
On April 1st 2011 I released TreeComp 4.0 b27. It fixes FTP downloads, that were broken since 4.0 b15 (Thank a lot Alex Howell!). Furthermore, I tried to make auto completion work more smoothly in the "Select Directories" dialog.
