I'm being hit (quite often) by that bug where you can't click on some indicators. It's easy to fix by restarting unity, but that usually also means running to the risk of upsetting some window on re-parenting (rare, but I'd rather avoid any such problems).

So, I know there is `unity-panel-service', and I'm guessing this might have something to do with the solution?

Is it possible to restart the unity panel (or the entire unity plugin) without restarting compiz itself?
