Apple has released iMovie 10.0.2 with fixes for unspecified issues that were causing the video editor to crash. The update also fixes two sharing issues: one that would cause sharing to fail outright and another where the Share button would not respond. Other changes include fixes for instances of blank project thumbnails and high-resolution images that appeared green, plus resolution of a problem where the Crop, Ken Burns, and Map features were not accessible on Macs using certain languages. iMovie 10.0.2 now requires OS X 10.9.1 Mavericks. ($14.99 new from the Mac App Store, free update, 1.94 GB)
Close Word Comments Easily
If you don't like how precisely you must mouse in Microsoft Word 2008 to delete comment balloons, note that you can Control-click (right-click) a balloon to pop up a contextual menu. From the menu choose Delete Comment, and you're done.
Also, to get rid of all comments at once, choose Tools > Customize Keyboard and set up a keyboard shortcut to go with the DeleteAllComments command, available in the Tools category. Oddly, there's no Delete Comment keyboard customization option that I can find.
