Modals and Timeouts in IE

Hey guys-

Need some help with making this work in IE.

In FF it is so that when you mouseover the image, it loads an iframe in a modal window after (X) milliseconds. When you mouseout before the timer reaches (X) seconds, it stops the iframe from loading. THIS IS WHAT I WANT.

But with IE, it doesnt stop/reset the timer on a mouseout. It continues to load the iframe after i leave the image’s area. THAT IS MY PROBLEM.

How can i fix it? Ideas?
