AFAIK things behave normally on the machines (I'm not there right now,
so can't test this, but I've had no trouble in the past).

Using "color byelement" (at the command line) in the middle of the demo
straightened things out at least for the frame being looked at.  I'm
_not_ sure but seem to recall that things got messed up again at a later
point.  

I figure I can deal with it by simply adding the command at places where
it is needed, but I'm really curious why it arises at all.

The demo is the "latest" version of the one I sent to you earlier.  I'll
send it under separate cover to you so as to not clutter up the list.
It depends on 2ace.pdb and ach.pdb being in the same directory as the
demo script.
