    ShellButtonBox: only listen to button 1 and single clicks
    
    Only mouse button 1 is supposed to activate button controls; other
    mouse buttons should do nothing unless there is a context menu.
    
    Checking the click count is important, since double-clicks will
    otherwise look like unpaired button presses.
