I have a div that acts like a drop-down. So it pops-up when you click a button and it allows you to scroll through this big list. So the div has a vertical scroll bar. The div is supposed to disappear if you click outside of the div, i.e. on blur.

The problem is that when the user clicks on the div's scrollbar, IE wrongly fires the onblur event, whereas Firefox doesn't. I guess Firefox still treats the scrollbar as part of the div, which I think is correct. I just want IE to behave the same way.
