i get two drivers from their drivers page for the Quadro FX 1700:

Graphics Driver: 169.96 for Win 64 This is the one I have installed Date: June 6, 2008

Performance Driver 176.06 for Win 64 Released July 11, 2008. This is a newer driver, I'm wondering if I should switch to this one.  I'm getting the occasional black box on pop up menus since Vista 64 installed some updates, everything is still working the black boxes are just anoying and the dialogue displays if I move the mouse along them.
