How to lock up your Intel Mac completely
1. Launch Word.
2. Connect external monitor.
3. Do stuff for a while.
4. Disconnect external monitor.
5. Use Cmd-Tab to switch to another app.... BAM! You done been frozed up.
This had been vexing me, until I finally caught GeekTool putting the message from the Console (a crash reporter) onto the desktop... apparently Word must be informed of any monitor activity. Once an external is disconnected, it starts to get cranky.
Bug or feature? Did MS put the bug in to intentionally crash my Mac? Let the conspiracy theories begin!
Anwyay, try it, lots of fun. Thank goodness for web-based work (no appreciable loss of data-- just a real PITA).
