While we are on this topic, enabling refraction on my computer (g key) crashes the projected water test with the following error:

Nov 17, 2007 7:54:33 PM class jmetest.effects.water.TestProjectedWater start()
SEVERE: Exception in game loop
org.lwjgl.opengl.OpenGLException: Invalid operation (1282)

   at jmetest.effects.water.TestProjectedWater.main(TestProjectedWater.java:80)


I have two nVidia 8600 cards (not sli'ed) with the latest drivers.  The error is pretty clear, but I was a little suprised my cards didn't support it.
