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)
Avoid Long Hierarchical Menus
If you right-click (or Control-click) on some item, such as a file in the Finder, and one of the sub-menus has many options (Open With is a frequent culprit), it may take several seconds to open, even on a fast machine, which is annoying if you did not actually want that sub-menu.
The trick is to not pull the cursor through the menu, but in a curve around it, so the cursor does not touch any menu items until lower on the list where you wanted to go.
