This is a strange one. I have made no changes to my system (XP SP1, nVidia GeForce MX4000, 512MB RAM, Athlon XP2400) or to my settings, but the screen resolution when I'm online has suddenly changed to what looks like 800x600. My desktop and all other apps are displaying at the desired 1024x768 and my nVidia settings in my system tray, even when I'm online, show that my resolution is set to 1024x768. A few nights ago I upgraded my display driver while downloading the Battlefield 2 demo, but that's not when the problem started. Spyware and virus checks are negative. (BTW, put this under the Windows XP topic heading, because it was all I could think of.)
