On a Win XP system, I must have accidentally selected some sort of desktop scheme in which all previously white Windows background areas are now black. Considering the text is also apparently still black, I cannot SEE anything in order to get back to the display properties to change it. Is there some other way of getting the display properties back to the default settings where I can see them again? Graphics show up fine, it’s just the formerly white Windows backgrounds that I can’t navgigate because I can’t see any text to click on.
