I'm having the same problem since I installed Windows 7 on my computer. I'm running Windows 7 64bit RC1 Build 7100 (EN-us) and if I start Windows while my second display is off, then my first display is blinking and the desktop cannot load proparly (the wallpaper is all black and my gadgets are all gathered and the top left corner).
For the moment, the only solution I found is either to come back to one single display or make sure my secondary display is on when I start Windows 7.
Does anybody experienced the same issue ? Is there any fix for this ? Is it more an nVidia driver
issue (I'm running official nVidia ForceWare drivers
V190.38) or a Windows 7 issue ? Notice that I never had this problem with Vista before (32bit or 64bit).
Any help or advice would be appreciated.
