Title: AccuRender and Matrox G400 cards

General instability in AccuRender can be caused by poor OpenGL drivers.

  
The problem I could identify is the dual head display. (I am using
the 5.30.007 driver.) To fix, go to the Matrox display
property setting, and click in advanced dialog box. You should be able
to get in to the control over Dualhead Tab. Click to turn the dual head on.
(Enable the last option.) After you reboot the system, go
to the display property and setting tab again. Now you will see the picture
of two monitors labeled no.1 and no.2 one with color. You then should 
double-click the one that is in black and white. You will be notified that this
monitor will be part of your desktop. Click yes. That's all there is to
it. Everything should run fine for AccuRender 3. 

You can now use AccuRender 3 with G400 Dual heads with no problem, freeze, 
or system hang when loading the model or orbitting. Hope this will
be helpful for many users.
