[IDV #CLJ-965783]: webstart IDV 2.6u2

A little more followup on this after some google searches:

- Only OpenGL 1.X is supported under Remote Desktop with XP and Java 3D uses 
OpenGL 2.X.  

- Using Java 3D 1.5.2 (which is shipped with IDV), if the required version of 
GL is not available, it will default to DirectX (D3D) and you should see a 
message like:

CONTEXT_CREATION_ERROR: Renderer: Error creating Canvas3D graphics context
graphicsDevice = Win32GraphicsDevice[screen=0]
canvas = visad.java3d.VisADCanvasJ3D[canvas0,0,0,681x464] 

so it looks like you are using an older version of Java 3D (which didn't do the 
auto switch).

- But DirectX is not supported under Remote Desktop either unless you are 
running Windows Vista or Windows 7 on the server.

So, it doesn't look like this is possible using XP.  You could set up a VNC 
server on Bert and use TightVNC instead of Remote Desktop.
