Error Message When You Click on Settings Tab (KB891387)

A dialog with the above message appeared on our Gateway Solo laptop

yesterday after a "helpful" person at work assisted my wife in connecting

the laptop to an LCD projector.

A usable interface between the laptop and projector was never achieved -

seemed to be a resolution issue as best I can understand.

KB891387 states the issue is resolved by SP2 (which we had installed on the

laptop prior to the above described incident).

KB891387 offers a "hotfix" which I obtained from MS today, endeavored to

run, and got a dialog that "Setup has detected that the Service Pack version

of this system is newer than the update you are applying - there is no need

to install this update".

I then reinstalled the driver for the ATI Rage Mobility which cleared the

KB891387 error message but now Settings in Display Properties shows

"(Multiple Monitors" on ATI Rage Mobility and does not offer a way to select

only one monitor.

Device Manager shows three "default monitors" - I deleted two of the default

monitors in device manager, rebooted, and now Device Manager again shows

three "default monitors".

Trying to fix this without a reinstall of the operating system.

Any help appreciated.
