Launch game - black screen

Sometimes I launch a newly installed game and the screen goes black and stays like this. The problem is Comodo is prompting permission in the background behind the fullscreen.
The computer won’t repond to ALT-TAB, CTRL-ALT-DEL or anything else, leaving user to hard reboot or wait 5-10 minutes for the application to give up/crash out.
When this happens is there any way to bring the Comodo prompt to the front, so I can grant permission to the application?
