gl_TextureMatrix on NV

[eyebex]

The following vertex program

(4) : error C1020: invalid operands to "mul"

Am I doing something wrong or is this is a bug / limitation of current NV drivers (I'm using 61.12 on a Quadro FX 500)?

You need to tell your shader what texture matrix you acutally want to use, for example :

coord=gl_TextureMatrix[0] * gl_MultiTexCoord0;

For the texture matrix of the first TMU.
