Whenever I right-click something in windows explorer other than favorites, libraries, computer, or network (the main headings in the left pane), the drop-down menu does not appear and an error pops up "windows explorer has stopped working" - "windows explorer is restarting". Once those both close the icons on the desktop and taskbar itself blink off and back on again. Is there any way of finding out what is going on when I right click and this problem ensues?
