Thanks, Scott! Your observation should be a good big hint at where the
problem lies, though I don't yet see where this leads.<br>

The following crashes hard, at least on Vista (and on XP):
    f = frame()
    b = box(frame=f)
    b.opacity=0.3
The following doesn't crash:
    f = frame()
    b = box(frame=f, opacity=0.5)
    b.opacity=0.3

Checking a bit further, the following crashes:
 &gt;     f = frame()
 &gt;     p = sphere(frame=f, opacity=1)
 &gt;     p.opacity = 0.99
 &gt; The following doesn't crash:
 &gt;     f = frame()
 &gt;     p = sphere(frame=f, opacity=0.99)
 &gt;     p.opacity = 1
 &gt;     p.opacity = .3
 &gt;     p.opacity = 0

So, a work-around is to create things you expect to tweak opacity
on as .99 opacity.  This doesn't get to the root cause, but does let
you move on.
