Calendar Event Alarms

---

I noticed that every time an event reminder goes off on my Tab it starts an alarm that just keeps going off till deactivated. On my phone it would just give me a simple notification sound. Has anyone else noticed this and have you found a way to disable it? I have it set to status bar notification under set alarms & notifications, but I still get the actual alarms (and its a rooster crowing which is quite annoying when I have stepped out for a smoke and it is just going off in my office.)

Thanks in advance for any light you can shed on this...
