Keyboard lockups with OSX 10.8.2
After the 10.8.2 update, keyboard input is hanging intermittently on my 2011 MacBook Air. It occurs in several applications (have tested with Safari and App Store) and often when switching windows or input fields. The keyboard input just stops working for a few seconds, then some of the typed text is input at the cursor.
Also, sometimes when opening a new tab in Safari, a window pops up complaining about a bluetooth headset. Maybe this is linked somehow?
Anyone else experiencing the same?
MacBook Air, OS X Mountain Lion (10.8.1), 13-inch, 128 GB
