After a fresh install of my system and installing Zone Alarm 5.5 I notice I am getting a severe studder whenever I run the game MS Flight Simulator 2004. It occurs about every 10 seconds and lasts for around 1/2 to 1 second in length. If I shut down ZA it runs smooth again. The moment I startup ZA it resumes. I have to be completely out of the program... just "locking" the internet does not work.

Has there been any reports on this happening. Could it be related to a service working behind the scenes with ZA? I never came across this issue with the older version of ZA (ver4?)

Thanks
