I'm running Windows XP Pro. When I right-click on the desktop, it brings up the display properties box, but there are no tabs. The only thing that shows up is the Theme tab. I can, for now, go into Control Panel and change some things through the Appearance and Themes category selection. But I can't change the monitor, for example, to change the refresh rate for the monitor. The flicker is driving my eyes crazy! Please help! How do I get the tabs back so I can have my old desktop back? Thanks!
