I recently tried dual monitor with vista 64, yesterday I upgraded to win 7-64. I'm still having the same issues as before with dual monitor settings only showing on one monitor.

The quick and dirty: 3.4 g proc, 8 g ram, geforce gtx260, win 7- 64 bit.

The settings:

Display monitor @ "1" (2 screens) Framerate 60

Disp mode: Piecewise Cubic

Multidisp mode: shared

Http DL:check                                                     Silent mode: check

Render Frames: check                                         directdraw mode:blank

keep renered frames:check                                  never skip: check

negative vote deletes sheep: checl                       debugging log:blank

v-sync:blank                                                       show attribution:check

reverse monitor order:blank

i may be missing something simple, so let me know.
