Vista - Vista Media Center focus/window behavior

I am using Vista Home Premium and have 2 19'' LCD monitors and a 32'' LCD
TV. I have the ATI profiles on my x1950pro card set to let me switch
between having both monitors enabled when I am using the PC and having one
monitor and the TV enabled for watching TV.

The problem that I have is with mouse and window behavior. When Media
Center is opened full screen it takes control of the window focus and locks
the mouse on the TV screen. I can ALT-TAB out of this to allow me to still
use the monitor while the TV is playing full screen by disabling the always
on top option in MC preferences. However, when Media Center is not the
window in focus, most of the remote control options won't work, and those
that will take the screen focus back over again.

Is there any update, download, 3rd party add-in, whatever that will let me
do the simple task of running MC as a TV while still working on the other
monitor like I described?
