error on page with pop up in TOC

[odelein]

I use the TOC calendar on my web site with pop up onClick. Everything is fine with Firefox but when i try in Iexplorer, It display an error on page in the status bar. By clicking on the events many times, i get the pop up to be shown but still with the error. I turned off the pop up blocker in Iexplorer and get the same result. With Onmouseover, eveything is fine in both firefox and Iexplorer but i've been told by a Mac user on Iexplorer(Mac) that the pop ups didn't display properly.
Here's a link to my calendar:

I see everything without an error using IE 6. Did you try clearing your cache?

Thanks for your help , but that wasn't the problem. As bizarre as it may seem, the yahoo toolbar that i had just installed in Iexplorer was the problem. When I disabled it, everything worked fine.
