Vista - Two Monitors - Only one is 'waking up' from sleep mode

Hello,

I am hoping that someone can help me with this issue. I have two Viewsonic
2030B monitors attached to a NVidia Quadro 3500 graphics card. I have all
the latest drives (all are signed) and I am running in Vista Ultimate 32 bit
version.

Everything is working fine and the monitors are extended properly, etc...
but... if I put the computer to 'sleep' that is I use the new option to 'save
your session and put your computer into a low-power state so that you can
quickly resume working) then only 1 of the moniters comes back on when I hit
the power button. Both are 'working' that is the system thinks I have two
because the cursor disappears off of one... but nothing I do seems to affect
this. I have tried all the different power scemes and settings that I can
find to no avail... this is frustrating because it means I have to literally
shut the machine down every time and I can not use this feature. The
moniters work fine from boot and in every other circumstance.

Any ideas?

Thank you

Terry
