I am running a 1 gh p3 with Abit vh6-ii board. 512mb ram.XP Pro. When Zone alarm (free) needs to ask permission for internet access for an app, it does nothing until I hit alt, ctl, del. Then The Zone alarm interface comes up along with the task manager. I am effectively locked up, and I cannot get out of this without pressing reset. I uninstalled Zonealarm and instaled Zonealarm Pro (trial), Same thing. Uninstall. I just purchased and installed Norton Internet Security 2003. Get all done, same problem. Any comments would be appreciated. Thanks, Ron
