Hi Mike-

Sorry for the delay in responding.  This fell through the cracks.

Changing the memory for Java shouldn't affect the graphics card at all.
Does the problem go away if you set it back to 512m and create the
same display?  Is the complete message:

Java 3D ERROR : wglGetExtensionsStringARB not support !
 - The specified procedure could not be found.
 
Fallback to use standard ChoosePixelFormat.
Java 3D ERROR : OpenGL 1.2 or better is required (GL_VERSION=1.1)
Exception in thread "J3D-Renderer-1" java.lang.IllegalStateException: GL_VERSION

Right click on the desktop and bring up the Properties dialog
for the display and go to the Setting tab.  Click on the 
Advanced button.  Do you have an OpenGL tab?  If so, is there
anything that indicates the version of OpenGL that it supports?

Updating the driver to the latest version should have fixed this.
I found this page that says that the drivers from Microsoft don't
have OpenGL support (news to me!):

http://www.intel.com/support/graphics/intel945gm/sb/CS-021517.htm

Try using the driver linked fro that page.  If that still doesn't
work, try to following:

Use the Help->About menu to bring up the About dialog.  Click on
the System tab and send that info back to us (this is automatic in
the next version).  You can click in the window, press Ctrl-A to
select everything, then Ctrl-C to copy and in your e-mail app,
press Ctrl-V to paste it in.
