Thanks Art, I tried your suggestion and indeed found a newer driver, but 
that did not fix the problem.  Then I tried Detect and Repair from the 
Help menu, and that did not fix the problem.  However, it made me pull 
out my installation CD, and while the "repair" was being carried out, I 
glanced idly through the Getting Started Guide.  And there I saw a 
mention of Preflight and CMYK separations (stuff I never use), and I 
thought hmmmmm, maybe I'm somehow seeing just the K separation???

Turns out that at some point I had attempted a Redo command by using 
Control-Y -- the opposite of Control-Z in most applications, but NOT in 
Acrobat.  Control-Y toggles "Proof Colors" and when you turn it ON, your 
colours go OFF.  Really intuitive, Adobe, thanks ;-)
