I'd be inclined to just check the clipboard function on mouseDown in 
the menu bar. That way you only need to update the menu when it's 
actually displayed. (Of course you'd also need to check the clipboard 
in the menuPick handler itself, because if the user uses a keyboard 
equivalent you won't get the mouseDown, but I think that's not a bad 
idea anyway, just on general principles - it's the last line of 
defense for error handling in case the clipboard content isn't what 
you thought it was.)
