Hi.

I don't have a solution, I'm afraid, but just to say that I also
noticed this when I changed my kernel to 2.6.12 and installed the
10.0.0.7a driver last night. I had previously been using the pwc
driver in the vanilla 2.6.7 kernel (don't know what version that was)
without the colour issue. I have a Quickcam 4000 Pro.

Regards,

Andrew.
