ZASS appears to lock portions of the computer for multiple minutes at somewhat random times. This has been gradually getting worse. First noticed in build 470. Updated in place to 483 with no major symptom change, just a continued worsening in what is starting to look like an exponential curve.
During the lockups there is low CPU utilization, but vsmon.exe shows heavy disk I/O with bytes read often in excess of 1GB during each halt. During these times the mouse pointer moves. I cannot do much else. Often happens when starting a program (the start menu stays up during the halt). Sometimes I can restore the Windows Task Manager (from minimized), sometimes I cannot. It eventually clears itself if I wait long enough (varies, at times 5 to 15 minutes).
The problem stops if I shut down ZASS.
Dell Latitude D620, 2GB RAM, 100GB disk. WinXP Pro SP2 "current" (KB951748 installed without symptoms and then uninstalled before updating to build 483 -- all this had no noticeable affect on lockups).
Any ideas what's going wrong and how to fix it? I tried ZA email tech support before realizing how slow it will be.
