My main work program is an old dos based program. After I updated to ZA 10, my dos program would no longer work correctly. If I disable ZA, then it works. I had no problems at all before the upgrade. Every time the dos program tries to update one of its databases, access is denied.
Any ideas please?

Windows XP
ZoneAlarm Extreme Security version:
vsmon version:
Driver version:
Anti-virus engine version:
Anti-virus signature DAT file version: 1056145920
AntiSpam version:
ZoneAlarm Browser Security: 1.5.311.0

Thanks for any help
