I was wondering if the following VMD-1.8.5 GLSL error message is something
I could correct? I'm running suse 9.3, kernel 2.6.16.21-0.25-smp and
Nvidia driver 1.0-9746. I liked using GLSL in VMD in the past since it
gave me a quick view at what a rendered shot would look like. I looked in
the NVnews forum but didn't see any answers. The kernel nvidia driver
message listed below seems related to having VMD-1.8.5 running and using
the middle mouse wheel. It is a strange error I've only had crop up with
these versions of nvidia and vmd together.
Thanks,
Dow
