Sorry to repost over here but there are very few readers in the other Treo groups.

Does anyone know how to disable reminders in the Calendar application? The problem is that TreoAlertMgr nags for EVERY type of message, whether it's voicemail, email, SMS or a Calendar reminder.

I don't believe this was the case on the Treo 300. Only SMS, email and Voicemail alerts were repeated. I don't ever remember having to ack a calendar reminder to stop AlertMgr. I suspect the problem is due to the new OS 5.x alert system.
