I'm using 6.0, if that helps.

There must be something in the way VM is called that sets the device
visual. Maybe someone out there knows a way to tell VM which visual to
use.

I'll try that on my machine, but I was hoping to be able to package
this program, which means that other users would have to do the same
thing - more work than I want the end user to have to do.

One more thing- if I compile this thing in say IDL 6.2, will VM be able
to interpet the program correctly? i.e., if I compile it in 6.2, and a
user runs it in a IDL VM that is packaged with 6.0, will it find the
correct visual?

Oh those IDL blues . . .
