Hi all
first off, thanks Tom for a terrific new toy!
now for David's comments...

Looked like you didn't have any/good OpenGL support with your other
drivers. You must not run GEM or PDP much, eh? ;-) Try "glxgears" with
each set of drivers loaded to see the performance difference.

I can back this up, but there is a good reason for it. See below...

Also true here.
The reason is that the window is called into creation when the wvvw
library is loaded, not when the object is created. This differs a bit
from the GEM/PDP paradigm, where the display can be created and
destroyed, and takes some getting used to, but I wouldn't consider it a bug.
Interestingly enough, multiple objects [reading different arrays] make
multiple tracks in the window, which are individually selectable.
Super-cool!

Hasn't happened to me yet....
