Hi hrbud - have a look at this thread:
http://forums.comodo.com/empty-t16971.0.html;topicseenIE7 is a bit more versatile and people often want to restrict it more. BTW, you may want to edit the entry for IE7 if you just clicked Allow. There is a more appropriate profile "Web Browser" that you can apply to it. Find it on Firewall>Advanced>Network Security Policy>(locate the IE7 entry and select it)>Edit>(select "Use a Predefined Policy" and select Web Browser from the drop-down). Click Apply and Apply.
