In NVIDIA advanced settings, I think there are some options (sorry I do not have a windows machine), you may need to change settings. See first post here http://www.gnutellaforums.com/window...w-i-fixed.html Also the 2nd post has a suggestion to drop Java back to Java 1.5 after uninstalling Java 1.6, however that would prevent you using the new LW 5 beta if your machine supports 64-bit java 1.6

I was told by several people outside of the forums about the nvidia 8800 that the advanced options are reknown to cause problems. Disabling these options. I cannot remember which one it was. That was a year or longer ago I was told. Running in some kind of environment.
