Problems with nVidia Quadro NVS 160M on Windows 7

Is anyone else having major problems with external displays on their E6400/E6500s with nVidia graphics running Windows 7? I'm having the following issues:

1. When I come out of sleep after docking, the monitors sometimes cycle in and out of power save mode. Depending on the situation, I can fix the problem by opening and closing the lid, going back into and out of sleep mode, or restarting.
2. I also sometimes get a blinking mouse pointer on a black screen when coming out of sleep mode. Whenever it blinks, it moves back to the center, so if I move the mouse around, it just goes back to the center on the next "refresh." This actually happens when undocked too.
3. I have two 2408s running on DVI, and when I haven't rebooted for a while, the card refuses to let them both run at 1920x1200 at 32-bit color. I have to bump it down to 16-bit color, or one or both of the displays will keep on going back to 1024x768 whenever I try to set it to 1920x1200.
4. I currently have artifacts on the screen -- lines going vertically down the display, probably about 22 evenly spaced across. They only show up on one of my two displays.

I'm not sure how many of these problems are problems with Windows 7, the beta nVidia driver on Windows 7, the graphics hardware, and/or the LCDs themselves. But I'm wondering if anyone else has any of the same problems.

 

the driver you get from windows update is a bit . i installed the latest from laptopvideo2go via "have disk"
