Just wondering if anybody has experienced problems with the GLSL
rendering in the new version of VMD...

I just downloaded and installed it, and tried that feature, andI got
the following message:

Warning) GPU driver failed to compile shader:
Warning) C:/Proteins/VMD//shaders/vmd
Warning) This GPU/driver is buggy, or doesn't fully implement GLSL.
Warning) Set environment variable VMDGLSLVERBOSE for more info.
Info) GLSL rendering mode is NOT available.

as expected, if I use the GLSL option I got the message:

Warning) OpenGL Programmable Shading not available.

I have a graphic card NVIDIA Quadro NVS 285 with the driver
(the latest version, as far as I know...) In the past I used GLSL VMD
1.8.5 without problems...

Any ideas??
As usual, thanks for your help!!
