First, try this:

Open Internet Explorer and click on Tools > Internet Options.  Click on the Advanced tab and put a check mark next to "Disable script debugging" and put a check mark next to "Dsiplay a notification about every script error".  If the problems are due to coding errors on the web page, which you can do nothing about, then this will stop the error messages. 

If this doesn't fix the problem, go the following message and take the steps to remove all spyware and web parasites from your computer:

ERROR!  Looks like you had an erroneous eruption, Volcano!

YOu are wrong to say: "and put a check mark next to "Dsiplay a notification about every script error". 

This will not stop the error!

To clear up any confusion, It should be: Make sure there is no check mark next to "Dsiplay a notification about every script error". 

You are correct.  After having typed that same sentence into this forum several hundred times because no one seems to be able to use the search function, I was bound to mess it up at least once.
