How to use ZoneAlarm the right way
I just found out later this evening why I can’t load my newly installed Yahoo Messenger. I simply missed this tiny security feature in ZA which cause a major impact on the stability of my applications.

What I did was I reinstalled YM while ZA’s program control was set to Low (learning mode).
I let ZA determine which components of my YM must be given access in order for it to work correctly. Then, when everything seems to be working right, I switch the level back to medium and after a few minutes, im back online chatting with my friends.
