Changing Main monitor in Vista.

[mynewromantica]

I am running Bootcamp on a C2D iMac. I have an extra 24" monitor. I prefer to use the lager as my main monitor. I can't seem to find out how to make the second monitor my main one. I opened display preferences and it has a check box for my iMac's display that says it is the main monitor but it is grayed out and won't let me uncheck it.

Any ideas?

This happens with Windows sometimes. I had this exact same problem on my work XP machine. To fix it I went into the graphics advanced configuration and changed it there, for my graphics card provider/driver. For integrated Intel graphics, this'll be in a control panel called "Intel Graphics Options" or something like that. For nVidia and ATI graphics there's a similar control panel.
