OK this is a weird one but not critical (fortunately). Many times when I do something and a small box appears (for example view what the volume setting is at or right click to delete something) the little box (with the word "delete" in it) stays on the screen no matter what I do. Even if I close the browser it still is on the desktop. Yes it goes away if I shut down the computer but may reappear when I delete something next time. Any ideas what to do to solve this or is it just cooties in the operating system or display board?
