The problem is the following:
1. Open Synchronize Dirs dialog for two folders large enough to be compared for several seconds.
2. Turn the by content checkbox on.
3. Press Compare button.
4. While comparing of dirs is in progress, double-click some line with non-equal files (that are already compared) to compare them by content in a separate window.
5. Close the 'Compare by content' window by pressing Esc key.
6. The process of comparing files by content suddenly stops in the Synchronize dirs window, some files remain not compared and marked with red question sign ? . If I press Compare button again and wait patiently for the process to finish, all files are compared - so, it's not a problem of inaccessible files, but really a sudden stop of comparing for some reason.
All this seems so as if pressing Esc key not only closed the Compare by content window, but was also passed to the Synchronize Dirs window - and this stopped the comparing process (as if someone pressed Esc there, in Sync Dirs dialog!).
As I mentioned at the beginning, this is not 100% reproducable. Sometimes it happens, sometimes not.
