I don't know if any one else has seen this happen or not...but I was trying
glow with a box object (with zero on the ambient finish setting), and the
box acted like it had a very high ambient finish setting.  I deleted the
glow (it was being used in a light source) and the same thing happened
again.  I quit megapov (windows version) and started the regular version of
povray.  after getting rid of the version statement, same thing happened.  I
had run a test box before messing with the glow, and it worked normally.  I
finally rebooted the machine, tried the box without the glow, and it finally
worked.  curiously, I tried a sphere with ambient set to zero (post glow,
pre reboot) and it worked normally.  I also tried an isosurface sphere and
cube during this mess, and they acted just like the normal box and sphere
object.  Any one have any ideas on this?  Is it just side effects from a
buggy glow thingy (type 0 by the way)?

Which version of MegaPOV are you using?

I don't think it is the glow patch...probably a stray pointer modifying 
something it shouldn't, and I think the glow patch works properly there. 
Can you reproduce it? Does adding the glow back in induce the same 
problem?

Well, I tried reproducing the problem today, guess what?  Didn't show up.  I
tried the same code again, and MegaPOV worked properly.  I am assuming that
the ambient level problem was caused by separate program poking its binary
where it didn't belong........I will let you know if it happens
again....sorry for this (apparently)false alarm
