since yesterday's update my comodo fw has gone crazy

I’m running Vista Business 32bit, cpu is Intel Core2Duo 2Ghz.
I downloaded the latest update yesterday, since then the popups keep coming if I want to allow already known programs to access the screen directly… For example, every single time I start up Total commander, it asks me over and over again. And it doesn’t even say the name of the application, it says “could not be recognized and is about to acces the screen directly” it does not say what could not be recognized. And asks everytime, also randomly with other programs like Firefox, and also the same way, without mentioning the name of the exe file.

Your best bet would be to do a Complete uninstall and reinstall using Revo Uninstaller in advanced mode. When you say you downloaded the latest update di you do that through Comodo’s auto updater or did you download the entire new package?
