The latest version
of ZoneAlarm (6.5.737.000 running on Win2000 Server) crashes on an almost daily basis.
The first error message I see is "The instruction at 0x7800FFE7 referenced memory at 0x00000000.
The memory cannot be written."
Hope you will fix it soon.

Operating System:Windows 2000 Server/Adv Server
