Fullscreen mode is kaput

[FlyingWren]

We're getting weird performance with both

viz.go(viz.FULLSCREEN)

and

viz.go(viz.HMD)

on our Matrox Parhelia machines. When we run a script with this, everything at first glance loads fine, but then the main rendering window (the 'worldviz' window) immediately minimizes itself. If you click on the task bar icon of it, half the time the program will go on acting fine, and the other half of the time the display gets really, really distorted and bizarre, and needs a reboot to fix.

For now, we just start with viz.go() and press F2 (which is an equivalent workaround).

We run fullscreen modes on our GeForce4 card without incident, so I can check to see whether the same behavior is exhibited there (though I seem to doubt it will show up).

PS: are viz.go(viz.FULLSCREEN) and viz.go(viz.HMD) equivalent?
