Sorry, I should have said what version(s) of Ghostscript I've been
using.  I've tried almost all of them, from Bill's 2.6.2 on Puma to the
3.3.3 I compiled myself from the GNU ftp site, to the 4.0.3 from the
NetBSD-Amiga/contrib archive.  They all give me the same blank screens.

Do I need a special lib.b from Puma?  I've never had any problems before,
and I thought that I had compiled GS to use its own FPU-less routines.
I'll try it out anyway, I guess, but I have a feeling that's not the
problem . . .

Thanks for trying to help Colin.
