Fiber script vertex color problem

I posted a summary of this to the Fiber script thread so RipSting will be sure to see it at some point, but I wanted to see if anyone else has encountered this.

I can’t seem to get Fiber 2.02 to use my vertex colors. I’m turning the VCol button on, but it makes no difference. If I import the sample mesh, it works on that. But on a mesh that I’ve created, it doesn’t. Furthermore, when I paint on the imported sample mesh, even a little, the VCol ceases to function. I’m using Blender 2.3.

Anyone else?
