Comodo firewall incorrectly identifies invisible applications

From time to time, Firefox takes a few seconds to appear on the screen when I launch it by clicking a link. Comodo correctly pops up with an “invisible application” warning, which is fine, but it then goes on to warn about every connection Firefox makes even after it is no longer invisible. (I have already set “allow all activities” and “skip parent check” for Firefox.) Comodo seems to never update its idea of which applications are invisible. I have to shut Firefox down entirely, and restart it, before Comodo will realize that it’s perfectly visible on the screen and stop nagging me.

Which version of Comodo Firewall Pro are you using actually ?
