Thanks for reminding me about this - it is readily reproducible, just
do a lot of typing while rolling the mouse around.  IMHO it's a bug
in tcl; the window reported for an event is not consistent with the
binding that caused the event.  In any case, with the benefit of
hindsight, I was able to come up with code that will make this problem
go away forever, and will check it in tomorrow morning.
