OK, here is the problem. For some reason on UNIX machines
the contents of the graphics buffer are not getting flushed
when you execute a graphics command with Call_Procedure.
I tried putting a FLUSH command at the end of the execution
and that didn't help. I tried an EMPTY, and that fixed the
problem. (I realized this was the problem, because if I
stepped through the code, everything worked perfectly!)

I believe I have seen this problem before. At least I
remember stepping through code and having things work,
but then NOT working when I just ran the program. I
probably should make a note of this. This is probably
not the last time we will run into it.

I'll have a new version up in about a half hour. If you
want to fix it yourself, put the EMPTY command at the
end of the FSC_WINDOW_COMMAND::DRAW method.

Cheers,

David
