Today i've installed build 3186. After installing, i've found that i can no longer navigate through my finder windows using the keyboard. Using the arrow keys to navigate around a folder has been disabled as has the ability to jump to a finder object by pressing the alpha key corresponding to the first letter of the object name. Further, objects can't be launched by the use of the CMD+<down arrow key>. Uninstalling 3186 (and rebooting) returns this ability. Re-installing 3186 again causes the keyboard control of the finder to disappear again.
