The changes may be minor in Apple’s release of iTunes 10.2.2, but they’re still welcome. The update addresses an issue when iTunes can become unresponsive when syncing an iPad, and a separate issue that could cause syncing photos with iOS devices to take longer than necessary. Also corrected is an issue with skipping video previews in the iTunes Store. (Free, 75.59 MB)
Option-Click in Scroll Bars for Jump Scrolling
In Mac OS X in general, and thus in most native Mac OS X applications, hold down the Option key and click anywhere in a window's scroll bar to jump to that spot (rather than scrolling one screen). If you like this behavior, you can make it the default in the Appearance preference pane. For "Click in the scroll bar to:" select "Jump to here."
