NVidia Quadro4 900 XGL can't multisample in a window?!

Does any one know if there is a NVidia Quadro4 driver for Windows XP that supports multisampling in a window? My code fails to find one, and the NVidia Pixel Format program from the SDK shows that multisampling is only available in Pbufs. Seems like the marketing claim that it supports full-scene antialiasing is specious. I’ve tried the 43.45 and 43.51 drivers. Any information will be much appreciated.

As I remember, you have to disable the “unified depth buffer” option in the display properties for AA to work on the Quadro series. They may have fixed this, but it was certainly the case a couple of months ago.

Thank you! I would have never guessed.
