Question : Closing an email causes Outlook to crash.

The GM of our company is running Windows 98 Second Edition with Office 2000 (fully updated). We run Exchange 2000 on our network. About two weeks ago, Outllook began behaving badly. Every time the GM opens an email, and then closes it, the act of closing the email causes Outlook to crash. This also happens when he attempts to send an email - although the email is successfully sent before the program crashes. I have attempted to repair Outlook, and also have uninstalled and reinstalled MS Office, but the problem still exists. Any ideas?

Here's the error message:

OUTLOOK executed an invalid instruction in
module at 0000:013f3ba2.
