Firewall crashed when Windows Live Messenger lost connection

Hi, I just installed Firewall Pro 2.4 (fresh install) today, everything was running fine (after it learned what applications to allow). However, when my Windows Live Messenger temporary lost connection, a Comodo window pops up saying I hit a bit. I filed the bug report, but would like to see if anybody in this forum has met this problem before. After the crash, IE7 can’t connect with the internet, and I can’t exit Comodo by right clicking the icon on taskbar. Evenually, I terminated cpf.exe and restarted Comodo, then everything is fine.

Any comments?
