Generally I agree.  My use case is not that trivial.  I use mouse3 from
Drew, that pops up a menu after the second mouse click, but only when
it was not double click (it depends on the time between).  He does that
by redefining `mouse-save-then-kill', which makes sense.  So when we pop
up the menu, the up event has already happened.

Makes sense, in general.

Great.  That fixes the problem in general, as well as for mouse3.
Thanks!
