I get about half my alarms in iCal. The program is open. The other appointment I had scheduled for today gave me the alert, yet the haircut alert never happened. This looks pretty simple to me. Does anyone see a reason why this wouldn't give me an alarm 1 hour before the haircut? Thanks. I take it I'm the only one having problems with alerts not alerting? Once again... Not getting To-do prompts. I see no reason, based on this screencap, why this shouldn't have alerted me.
