Hi, I just installed Parallels Desktop 4.0 for Mac and Windows XP SP2 on my mac OS X 10.5.7 that possesses a NVIDIA GForce 8800 GT video card. When using the mac OS, I have a double screen but I just can't configure the Microsoft Windows XP SP2 to be displayed in a double screen. Could anyone help me to configure my Windows XP SP2 for a double screen display? thanks a lot!
