I am getting the same error message as well. The last thing I can remember doing is changing my default editor to FCKeditor, but changed back to the default Joomla editor after getting these messages. However, the messages continue to be reported only in IE.

It also appears my JAnewsflash module has stopped working only in IE, but continues to work in Firefox (named “School News” in right column). Please visit http://holyrosaryrams.org to see.
