Just an FYI regarding Comodo Firewall version 3.14.130099.587 within Windows XP (32-bit) Service Pack 3.
It crashed during editing within the My Network Zones window. Specifically, while three address entries within a network zone were highlighted and being dragged/copied (with the Control key pressed) to another network zone. The destination network zone was newly created and empty of addresses prior to the attempted copy.
Unfortunately, I cannot attach a crash dump file because the Windows crash dump file creation option was turned off.
edit (added the following info)
I did some further testing regarding the crash.
The crash could be consistently reproduced if AT LEAST TWO address entries were dragged during the copy to a newly created network zone (which is empty of addresses) AND the moving red GUI line that indicates the copy destination is drawn BELOW the “(add addresses here)” text.
