An off topic query. Have you found a situation that if you convert to B&W using the Channel mixer in PSP, the next time you open the image its back in colour even with the Channel Mixer in the layers. PSP version X by the way.

When I tried the Channel mixer and even rebooted the program, I did not find that it changed back to colour. It stayed black and white. I did however find weaknesses. The greys resulting were slightly on the warm side and pale colours were more white than a light shade of grey.

I compared with with a black and white conversion filter (16bit) on the same photo. There were more controls for adjusting the software filter and it produced better quality tones.
