This is even stranger: there are no idle loops, etc., but under 10.4.2, it uses upwards of 85% CPU time (and the fans come on for both my G5s and my powerbooks), but drops to virtually nothing under 10.3.x. This is a serious, but peculiar bug. BTW, Mark's solution won't work as I have no scripts associated with the slider (they all occur at the card level where the slider value is read).

I have encountered a strange system incompatibility.  Stacks that ran/
run fine under Mac OS X 10.3.x, produce the following peculiar
behaviour under 10.4.2 (whether using the MC or RR IDE).  I have a
slider in a group that also contains a default (throbbing) button,
which is to be clicked when the slider is in the position the user
wants.  All is fine under 10.3.x (i.e., the button throbs and the
slider tracks the mouse as the user slides it back and forth); under
10.4.2, the button s-l-o-w-l-y throbs (i.e., you can see each step of
the throb animation), and the slider no longer keeps up with the
mouse (i.e., it lags by a lot).  It is like the whole system has been
slowed down by a factor of 2 or 3 (i.e., 100 or a 1000-fold).  Yet,
other default buttons throb correctly.  (I have no other sliders in
these stacks).  It is clearly not my code (indeed, I have used this
group successfully since at least MC 2.2, and probably before, and on
all other versions of OS X).
