Weird--never even occured to me.  That explains why I had so much trouble
with it.  However, while the latest version (0.51.1) registers
ChildWindowFromPoint/Ex, it should never call the function (apps might do so
themselves).  Derek found another method to find children windows.

We'll have to update the register call, though...

Thanks,
