Basically, I'm having an issue with reminders in iCal popping up several minutes to at least a half hour after the time the event is set to start. iCal is set to automatically create reminders for five minutes prior to the beginning of any new event. When the calendar is synced to iCloud and then to my iPhone, the alarms pop up fine in the phone, but still delay on my Mac. Anybody know what the deal could be? The problem began when I installed Lion last year, and 10.7.3 made the issue more pronounced. I've already tried deleting my calendar's cache. The only thing I can think to try would be a clean install of Lion from my USB backup of the installer (I installed it over 10.6).
