For some reason when I try to reply to, forward or create a new email when I
click on the To, cc or bcc buttons Outlook locks up and I have to go to the
Task manager and terminate the program. The same thing happens if I try
clicking on the address book in the message window. I can open the address
book in the main window of outlook without a problem.

Also if I open a contact group and try to add an existing contact to the
group this also locks up the program.

I have tried the repair feature and it finds nothing wrong.

Is there something I can try short of reinstalling the software which may or
may not fix the problem?

Thanks!
