I installed ZoneAlarm Internet Security Suite in my new computer running Windows Vista Ultimate. All went well but I am facing a problem of intermittent instability of the ZA icon in the icon tray. Sometimes the icon appears to be OK but when I pass the mouse pointer over it, it disappears and does not return until I load ZA again. Rebooting the computer may or may not solve this problem. I chose to have this icon always showing.
Another eventual problem is that True Vector Internet Monitor frequently is turned off by I don't know what and keeps asking if I want to have it running again. Of course the answer is always yes, but why does this happen?

Operating System:Windows Vista Ultimate
Software Version:6.0
Product Name:ZoneAlarm Internet Security Suite
