I am running ZoneAlarm Pro and since the last two upgrades I have been getting a Message - ZoneAlarm has encountered a problem and must close down followed by an appology if I'm in the middle of something. This is occuring several times a week at apparently random intervals. It gives no clue as to what the problem is and seems to work OK if I restart the computer. Has anyone else experienced this?

Operating System:Windows XP Home Edition
Product Name:ZoneAlarm Pro
Software Version:6.5
