Thanks so much for the replies guys. 

I actually got desperate and started fiddling with all the monitor menu settings (even the ones that I had no clue what they were for - lol!) and I happened to hit on the right one.  Some kind of auto adjust thing.  It fixed the problem right up...net browser, Poser, PSP, WoW...everything!

Phew!  big sigh of relief
