Before doing a clean install of Leopard my “Open With” menu was cluttered with duplicate entries (and I’m sure over time it will happen again). I’d right-click an image wanting to open it with Seashore and the menu would have Firefox listed twice, Seashore listed twice, Preview listed twice, and so on. It certainly didn’t keep me from opening with the desired app, but it was such a blemish on the beautiful OS X aesthetic. Well this month’s MacWorld magazine has a solution easier than reinstalling the OS. From the terminal enter the following (no spaces until -kill):

/System/Library/Framworks/CoreServices.framework/Versions/A/
Frameworks/LaunchServices.framework/Versions/A/Support/lsregister
-kill -r -domain local -domain system -domain user

Reboot and voila!, menus are duplicate free.
