Motorola KRZR K1m

I've noticed that my Krazr doesn't hold a "missed call" message after the small outside screen times out to black. Other phones I have used hold this information for when the phone is open. I now have to go to recent calls to see what I missed.

Can anyone else tell me if this works for them? The missed call indicator stays on the screen until it times out to black. Then, poof. It's gone when I recheck it.

Thanks
