I have NOT heard of anybody having problems with it at any of the forums that I am active in which is quite a few. The details were in the updates thread on Tuesday if you want to see what has been fixed. I don't use Zone Alarm myself so I can't give you my own experience with it though.
I had a pop-up from ZA announcing a new upgrade, 60.667.000. They recommend clean install for this one, which menas going through all the gyrations all over again. I am going to hide and watch for awhile on this one.
