I prepared this add-on to CrystalClear Interface 1.9 a few weeks ago, and it works like a charm for me. It’s a simple AppleScript utility that quits the Finder, turns CoreUI back on, and restarts Finder again.

I keep it in my Login Items so the Finder looks right every time I log in. If you happen to relaunch the Finder during your current session, you’ll need to run CoreUI Finder again. For such cases, I keep the utility in my Finder toolbar. CoreUI Finder is available in the Mars Downloads section, or from this URL.
