Randomly assign mesh colours in Max 2011

Hey all,

I have what appears to be a basic, but somewhat annoying issue with Max 2011.

I just built a new PC and downloaded Max Design 2011 through the AD student program (I'm an Architecture student, and had used up my activations of the 'non-Design' version).

I usually use the 'Assign random colours to new objects' thing when I'm working, granted I usually assign my own colours afterwards, but for quick blockouts, it's kinda useful to just leave it on random.

However, regardless of whether I have the random checkbox checked, Max always assigns a single colour to new meshes, and the colour only changes on resetting Max.

For example, I'll open Max, create a few cubes, they'll all be blue... click 'assign random colours' and create more... all blue still.

Reset Max, create a load of meshes... now all pink.

Etc etc.

Is this a screwed config file somewhere or have I missed a setting? Usually on a fresh install I don't have this problem.

Any ideas on how to fix it?

Thanks
