In most cases, you can ignore the message. Script error messages are displayed by Internet Explorer when there is a problem with the JavaScript or VBScript code on the website you are viewing. Occasionally a script error can be caused by an error in downloading a webpage, but more often it is an error in the webpage itself. You can however disable "script debugging" if it is happening on multiple sites. I would firstly though clear your "history" or at least cache, empty your recycle bin, reset your wifi modem if you are wireless, and do a safe reboot. If the problem persists you can disable script debugging in the "Tools menu". Click on Internet Options as previously advised[ reluctantly :)) ]and on the Advanced tab, click to select the Disable script debugging check box. And then click OK. If you need to clear notification about every script error in Internet Explorer, on the Advanced tab, "click to clear the Display a notification about every script error check box", and then click OK.
