TRACKING-POINTER :PRESENTATION-BUTTON-PRESS bug?

Running CLIM 1.1, Genera 8.1.1, it seems that the
:PRESENTATION-BUTTON-PRESS clause of CLIM:TRACKING-POINTER works for
left and right mouse button clicks, but *misses* mouse-middle clicks.
The :PRESENTATION-BUTTON-PRESS clause goes through the normal
presentation translator mechanism. What this means is that the
sensitivity for a presentation is controlled by the so-called "identity"
translator, which is the default translator you get for the left mouse
button. You also get right button clicks because the "menu" translator
is applicable whenever "identity"is applicable.
I know this explanation is probably not very satisfying, but I don't
really know what to do about it.
Evaluating the code below and running (run-test) illustrates the
problem. First click on "Generate A Presentation", and then click on
"Track Mouse". Clicking the mouse-left or mouse-right buttons while
the mouse is over the presentation executes the code in the
:PRESENTATION-BUTTON-PRESS clause, but mouse-middle clicks are passed
on to the :POINTER-BUTTON-PRESS clause.
Am I missing something, or is this a bug? If so, any suggested fixes?
It's a bug. I'm not sure exactly how to fix it, although I think I am
having an idea...
