Ambrosia has released Snapz Pro X 2.5.2 to fix an issue with accurately capturing the precise pixels of a selection and bring back support for several styles of image borders (which was excised in version 2.5). The update also improves the reliability of movie encoding, improves compatibility with both OS X 10.8 Mountain Lion and Retina displays, and adds Chinese and Russian localizations.

Disable Caps Lock
If you find yourself pressing the Caps Lock key accidentally as much as I do, note that you can disable it entirely in Mac OS X. Open the Keyboard & Mouse preference pane, click the Modifier Keys button, and in the dialog that appears, select No Action from the Caps Lock pop-up menu. You could remap it to another modifier instead, but that might make using differently configured Macs more difficult.
