The icon pictures have dissapeared, but the text for the icons remains.\nClicking on the text operates the icons normally. Start menu shows a black\narea where items should be, except for "All Programs" and "Log Off" and "Turn\nOff Computer". Quick launch icons pictures are not visible, but the buttons\nremain. Other users do not experience this problem. What can I do to\ncorrect this problem? Thank you for your help.
