Dialog with combobox with around 100 items getting javascript "stop running this script" when clicked on in IE only

I posted this a few minutes ago but I can't find it, maybe moderator didn't approve?

We are simply calling ajax to get html from an action then placing it in the div used by the dialog.  It has two comboboxes and one works fine with less than 20 items but the one with roughly 100 works fine when you use keyboard up/down keys but if you click on the dropdown to view it, IE throws some popup about "Stop running this script".  There is no script on the combobox that we call.

Any idea, pretty new to JQUERY.
