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)
Move the Dock Quickly
You may find it convenient to move the position of the Dock when working in certain programs or with certain files. Rather than choosing a different position from the Dock preferences pane or using a submenu in the Apple menu's Dock submenu, you can move your Dock to a different screen edge merely by Shift-dragging the separator that divides the application and document sections.
