The "Show Procedure" pop-up box gets turned on by hitting F10.  The window will show the procedure name before execution.  This is frequently turned on in error.    When you hit F10, the box to turn on the option is checked by default.  If you clicked OK to close the window without unchecking the box, you inadvertently turned the option on.  To stop this pop-up box from appearing:
  1. Press F10 again
  2. Uncheck the box
  3. Click OK
