Either a bug or incompatibility but ZoneAlarm appears to crash the computer every time after shutting down WAMP but not when starting. Problem is repeatable.

This behaviour only started recently so might be an XP update or ZoneAlarm update issue. But if it continues I will have to lose ZoneAlarm, not XP.

Stopping ZoneAlarm allows WAMP to stop and the computer does not crash on exit.
