Apple has released iMovie ’11 9.0.8 with a typically cryptic note about the update: “Addresses an issue related to third-party QuickTime components that could prevent iMovie from opening.” However, according to this support page, it appears that one of the third-party culprits is the 3ivx component (used to enhance compatibility with such camcorders as the Flip Ultra and Flip Mino). If you currently have 3ivx installed, version 9.0.8 of iMovie displays a warning dialog that explains how to remove the component. ($14.99 new from the Mac App Store, free update through Software Update or the Mac App Store, 1.08 GB)
Customize Open/Save Dialog Sidebars
You can customize the sidebar in an Open/Save dialog the same way you can in a Finder window: you can reorder the position of items, drag them off into puff-of-smoke oblivion, and even drag a folder from the dialog's list into the sidebar.
