When I try to open any audio file with windows media player I get this annoying beep and nothing happens. If I try to open up WMP itself I get the same annoying beep. If I try to open an audio file thats on the desktop I get the annoying beep, plus my mouse can no longer affect the desktop* *This requries more explination. I can not select a different icon, and right clicking anywhere on the desktop behaves the same as if I had right-clicked on the audio file. If I delete the audio file I simpley have no icon selcted and can not select a new one with the mouse. However the keyboard still works and I can select different icons using the arrow keys. The mouse works normally everywhere but the desktop. Even when I reset the preference to open the audio file with realplayer or winamp it still gives the annoying beep and the same affects on the mouse. However the icon refuses to change from a WMP icon to a RP/Winamp icon and I suspect its not changing the preference. Meanwhile if I click "open with: realplayer/winamp" the file opens normally and plays and there are no affects on the mouse. Any ideas or clues? The machine in question is an Emachines T2742, yes I know I need a different computer.
