Thanks for the feedback on the cards. The main reason I've wondered is due to all the weird display problems I've had in Vue(5 and 6) since switching to Quadro (no problems in other apps). Things like dialog boxes that pop back after closing... this happens to me a lot. The boxes aren't really there, I can't operate them. And clicking a new function clears it. Since this behavior occurs on both my machines, it makes me wonder what gives? Had the same problem in V5I on the 32bit system, until the later patches. Mostly it's just annoying, but couldn't help wondering if it was a clue to other problems. Guess not?
