I am running Zone-Alarm Anti-Virus, and I am encountering a problem using Works Spreadsheet 7.0 that only occurs when Zone-Alarm is running.
I can start up the Spreadsheet application and open a spreadsheet file ok.
However, if I go to Format->Number, the program hangs until I shutdown Zone-Alarm.
On the other hand, if I start up Works Spreadsheet without Zone-Alarm running and go to Format->Number, everything works ok.
If I then start Zone-Alarm and go back to Works Spreadsheet and go to Format->Number, it still works.

This is something relatively new, as it didn't happen with previous versions of Zone-Alarm.

Operating System:Windows XP Home Edition
Software Version:8.0
Product Name:ZoneAlarm Antivirus
