Strange Mouseover behaviour - Bug?

[leemcg]

I'm not sure it's quite just about rectangle bounding boxes. In my first example, I get pretty much pixel perfect mouse overs for the diamonds. It's only when the pop-up obscures the mouse over.

In fact I've thought about how this could be desirable behaviour...

If you have a mini photo, you want to mouse over to make it bigger, and you make it bigger on top of the mini-photo. You can no longer see the old photo, so where is the intuitive place to move the mouse to get rid of the large version - it's off of the large photo, not off of the small one you can't see.

(I have to find some terminology that makes explaining this easier!!!)

So I'm guessing it's deliberate. Maybe there is a hidden registry option to turn it off. Please....
