Nope, I'm not doing any stopping. I'm wondering if it is
because the sprite contains bitmaps, not sprites?
At any rate, the confusing thing to me is why down/up
triggers, but not click. According to the docs, it says:
For a click event to occur, it must always follow this series
of events in the order of occurrence: mouseDown event, then
mouseUp. The target object must be identical for both of these
events; otherwise the click event does not occur.
Seems to imply that the target is changing... I'll put in
some print outs to see if that is the case.
