2.4 Fuzzy Icon in Retina

Hi

FYI I just upgraded to 2.4 (OSX Mountain Lion / Retina MBP) and my icon is now all fuzzy

Restart your computer - it will be caused by a caching problem. (The new version has an updated icon with Retina graphics in it, but your machine is caching the old icon but finding parts of it missing.) This is a common problem when updating apps with updated icons on OS X, and restarting will fix it (or should do!).
