I'm on a PC. Again...my results, in PS2 on a PC, are baseline standard, NO
change. Baseline Optimized, 1% yellow added.

I disagree.
I just did what Jouni suggested, making sure I selected Baseline Standard /
Quality 12 Max at the Save As point as you indicated.
Upon re-opening the file the C100M100 had picked up Y1 while the M100Y100
picked up C1 as he'd predicted.
I can't explain why. I suspect it's some kind of math rounding error.
I'm running CS2 (9.0.2) on a Mac Pro. There are indications Intel Macs have
issues with basic math. This might be one of them.
