Freezing PC when alert

Hello. I have big problem. I already reinstall my system and install comodo. But sometimes when there is firewall alert when i choose allow then alert is stuck and whole system is freeze… I can only reset. It’s very annoying…

Do you have any other security products installed?
Even if you don’t, did there used to be any other security products installed on your computer?

Does this happen with specific programs you are getting the alerts for?

I didnt have any other software, also it’s totally random, sometimes even with system processes.

On what OS are you?

Windows 7 64bit

It’s already bug reported by someone : they should do something about that beacause it’s very annoying…

Please add your system details to that bug report.
