I downloaded and installed SP1 and thought everything was working okay, but Zone Alarm Pro seems to have some issues. I tried working with options and preferences , but some websites just won't open or function right. This site in particular is slow or not available. I finally got fed up tinkering around and uninstalled the program. I've got the XP firewall running, and I seem to be back to normal operation. I'd like to reinstall Zone Alarm because of its configuration options. Do you think it's my system or should I contact tech support at MS or ZA?
