I used TVRD in the Z buffer. That is surely an 8-bit
color resolution!

I don't think it is the same problem. I *know* I have
pixels with that value (some 300K of them!). They
just don't go transparent and I can't figure out why
not.

Cheers,

David

P.S. Let's just say I'm reluctant to spend much more
time on it and blow my cover about knowing everything
about IDL without having to do all the hard work. :-(
