Been using ZAPro for three years with win98se (I know..upgrade, upgrade) without problems. The latest version performs well for me when running but seems to have created a new shutdown problem resulting in the dreaded BSOD (at least 8 out of ten times). Email requests for help brought quick responses from Zonelabs but no solid info for fixing the problem. If I can't find a conflict with another app that is not needed I'll probably remove the new version and reinstall the previous until ZLabs resolves their problems. I'm just hoping that ZAPro isn't going to become bloatware. If it ain't broken don't fix it.
