Unlike earlier versions of Windows that only allowed a plain colour background behind the labels under the icons on your desktop, Windows XP allows you to make the background transparent so that the text appears as if it is directly over whatever background image you are using for your page. If the labels appear to have a plain colour background on XP and you want a transparent background then open the Control Panel and go into the Performance and Maintenance section. From there select System and then go to the Advanced tab. Go to the Performance section and press the Settings button. The "Use drop shadows for icon labels on the desktop" option needs to be selected.If you still have a plain colour background with this option selected then right click on the desktop, select Arrange icons by and make sure that "Lock web items on dersktop" is NOT selected.
