I have a laptop and an external monitor. When at my desk, my preferred setting is to use the external monitor as my primary monitor and extend my desktop onto the laptop display. I can easily set this up in the Display Settings control panel. When I first installed Vista, I was pleased to note that it remembered my settings whenever I connected to the external monitor (in XP I had to manually set it up every time).
However, at one point I was experimenting with the "Connect Display" feature on the Windows Mobility Center panel, which only lets you use the laptop as my primary display and extend onto the external monitor. Ever since then, when I restart or login, Vista discards my display settings and goes back to the Windows Mobility Center settings, with the laptop as my primary monitor.
Is there any way to force Vista to remember my Diplay Settings preferences, and forget about my WMC settings?
