I don't experience any of the problems you seem to have. I can split 8 and 16 bits-per-channel RGB images to R,G and B channels without any need to previously convert to CMYK. I can also switch from 0-255 to percent black in curves.
My working environment is CS4, Win 7, 64 bit AMD dual processor.

I've been away from printing for many months, working on an audio project. In the meantime, I upgraded to CS4.  My current problem is that I used to make separation negatives from a RGB file.  Now, as far as I can tell, CS4 makes me convert to CMYK before I can make separations.  Am I doing something wrong?  Did CS4 hide the process as it did with some others (making it impossible to switch between 0 to 255 ink and % ink in the curve dialog for instance).

Any help is appreciated.

ps  I did keep up with the messages while I was graphically inactive.
