Wasn't quite sure which of the sub-forums this would be best in, so mods, feel free to help

Like others, I've complained in the past about the barrage of calendar alarms that seem to pop up for some events. It seems like you dismiss an alarm, only to be hit by another one seconds later, and maybe even a third.

I found this to be the issue, at least for me:

I had Google Calendar set to issue a pop-up reminder. The Pre was also set to issue a reminder. And for good measure, I use Rainlendar sync'd to Google, which is also set to issue reminders. Well...sure enough, they EACH will do exactly as instructed! The real surprise was Rainlendar sending alarms along to my Pre through Google; pretty nifty, but annoying.

So, the moral of the story is: set an alarm on only ONE of your calendars, or you'll be hounded by all
