It's happened a few times, very annoying. The mouse cursor still moves, I can still SSH in, but killing apps does not seem to make them disappear from the screen. I'm going try LiteSwitch X (Cmd-Tab replacement) which has been suggested as a solution/workaround elsewhere...</p>HubertTue, 04 Sep 2007 22:21:00 -0000http://davidjrice.co.uk/2007/07/22/apple-macbook-pro-freezing-when-switching-application-with-command-tab.html#comment-16104375<p>This has happened to me twice in the past week and yes...I have an external display hooked up to my MBP.</p>Martin BakerThu, 23 Aug 2007 12:18:00 -0000
