[Bug] Sync Dirs: archive <-> folder with this archive

[Flint]

Occasionally I found that TC' Synchronize Dirs tool behaves strangely when I try to compare some folder containing a ZIP-archive with contents of this ZIP-archive. The archive itself is shown but has no checkbox for changing the direction, and is shown black, as if it was present on both sides, and it becomes hidden when I make the '=' button unpressed. Look at the screenshots below:

Of course, I know that it's impossible to copy some archive into itself, but the absence of this archive in the list of different files looks strange.

This is by design, so you don't try to pack the archive into itself, which would be the default since it's missing on the other side...

Ok, thanks for the explanation. I think, this feature should be added to the corresponding section of the Help file...
