Right, but does that mean the hscroll property of the mobile scroller 
must be true? Right now mine's false so I assumed it wouldn't even try 
to detect scrolling horizontally. I can change that setting of course.

But your solution and Scott's are very similar so it must work. I'll 
experiment with both. Thanks for the ideas, both of you, but I sure wish 
we could use a simple mouseUp to detect it. It would save a lot of trouble.
