I'm using CLIM 1.0 and MCL 2.0, both beta.

I've discovered a problem with clim:tracking-pointer.

I track the pointer and highlight the presentations it passes over,
taking care only highlighting when the pointer enters the
presentation, and dehighlighting when it exits. The problem is that
the exiting motion, it counts as a presentation movement, so the
pointer actually is outside the presentation after the motion.
In my case this means that the presentation is still highlighted after
the pointer has just exited, giving the user false feedback.

It also seems to be a disagreement between the :presentation clause
and the :pointer-button-press clause as to when the pointer is on a
presentation. When moving entering presentation and pressing the
button, I get a pointer-button-press event and not a
presentation-button-press event.

I've been debugging my code for quite a while and am quite sure that
something must be wrong with tracking-pointer. If it's needed I will
try to make some code that demonstrates the problem, so others may
verify the problem.
