Vista and NVidia Dual Monitor Issues

We just got a brand new Toshiba laptop with the NVidia GeForce Go 7300 video card. The problem is that there is a major driver incompatibility between Microsoft Vista and this card. The system does not appear to support dual-monitors. This is a major problem since this computer is for use in displaying SongShow Plus.

When plugging in the external monitor or projector, the laptop would immediately output the screen to the external monitor and disable the laptop screen. No setting changes would bring it back and obviously screen spanning was not possible.

In the sytem's "Task Scheduler" there is a process called "TMM" located under the MobilePC category. This needs to be disabled. Once disabled the system will refrain from forcing a switch to the external monitor.

With TMM disabled, all of the multi-monitor features now function, albiet rather questionably. Vista is not an operating system quite ready for prime-time. I'm looking forward to updates to both Vista and the NVidia card.
