Paint Skin Weights Tool - Not displaying paint

[doug-hines]

For some reason when I use my Paint Skin weights tool, the mesh does not go into a greyscale type shader.  Instead, it goes to what looks like a standard Lambert grey instead of the black and doesnt display weight values in the greyscale I'm used to.

Did I mess up settings somewhere?  I know I'm in Paint Skin Weights tool because I can see the bones when it goes into Xray.

Help please?

do you have a joint selected in the list ? if you don't, maya will display you the gray lambert and a paint brush cursor like a circle with a cross.

sometimes, even with a joint selected I get this bug too. I just reload Maya.
