If your mouse has not frozen up, you can access the Force Quit menu by going to the blue apple (upper left of your screen) and choosing "Force Quit".

If you can't get the Force Quit window to come up, you'll have to manually restart your machine. Press and hold the power button on your computer for about 5 seconds, this should force a restart.

user accounts.

The error is: "iCal can't save the event "EVENT TITLE" to the exchange server. The account can't be modified. To discard your changes and continue using the version of your calendar that is on the server, click Revert to Server. To save your changes on your computer until the problem is resolved. click Go Offline."
