Matt,

Thanks for posting your findings.  Just eyeballing your workaround seems that it would be an IE specific fix, as other browsers don't inherently suppor the global event object.  I am not sure it is worth the effort changing to code to fix what appears to be a bug with McAfee's product, as I would hope they provide an update soon.  I am assuming that DNN is not the only website affected here.  Please post any relevant updates to the situation.

Thanks so much PacaVista for getting to the bottom of this problem. Its been driving me crazy for a while. Let me add some search terms so other poor folks can find it too. I was searching for collapsible panels and visibility in IE7 and expanding advanced settings. Thanks
