I recently upgraded my HTPC with better hardware, Vista (using the term upgrade loosely), and a secondary monitor.
After the upgrade, I ran into a problem with Vista and secondary monitors...
If video is running on the theater screen, and the theater screen is set to the primary monitor. I was unable to switch my secondary monitor to the primary monitor without pausing the video on the theater screen to access the primary monitor's desktop.
So I wrote a small program to quickly change a secondary monitor to the primary monitor, without having to access the current primary monitor's desktop.Make Primary Monitor
When you install the program, you copy the desktop shortcut to all of your secondary monitors. Then anytime you want to promote a secondary monitor to a primary monitor, just double click the shortcut on the secondary monitor, the screens will blink, and that secondary monitor will become the primary monitor.
I may be the only one that had this problem, but for me, this has been a real nice addition to my HTPC.
I put up a web page with a download link and instructions...http://www.syaeger.com/PCUtils/
