While I second that 'good catch' in this case, I'd like to add the following, just for the record. The 'Get Info' vs. double-click Edit explanation doesn't work with older versions of iCal, where it always says 'Done' regardless of how you edit an event (Leopard, iCal 3.x), or there is neither 'Done' nor 'Apply' button ('Get Info' in iCal 4.x, Snow Leopard) and closing the Edit window enters the edit. Confused?
