Outlook 97 error message "ThorConnWndClass"

[Pat]

Yesterday my Outlook stopped receiving messages and
started to bog down my PC while it tried to pick up
messages. When I reboot, I have to manually close Outlook
(through the Ctrl+Alt+Del popup window) and then I get an
error message that tells me that ThorConnWndClass is not
responding. I have to click End Task to reboot. When I
reboot, the probelm is not fixed. I tried reloading
Office 97 but that has still not corrected the problem.

Has anyone had a similar problem and do you know the fix?

Thanks,
Pat
