Pioneer54 - I know I've had a problem like that before (not on this site, but elsewhere), and I've been trying to remember what I did to stop getting those messages.

Try to go to Tools, choose Internet Options

Click the "Advanced" tab

The 4th & 5th option under browsing is about displaying script errors - UNCHECK both of those boxes and see if you still get those error messages. (Note: depending on version of IE you are using, will depend if the instructions above are exact or not.) :-)
