I have 5 email accounts that I access viz Office Outlook.
When I switch between accounts, this box pops up:

an error has occurred in the script on this page.
Line: 78
Char: 1
Error: Library not registered
Code:  0
URL:  (long address.....)
Do you want to continue running scripts on this page?



Doesn't matter if I choose YES or NO.....but I have to choose one or the other to proceed!!

What's up? Help!
