I've got my Hero configured to do LED notifications for all my notifications. It seems to be working properly - the LED flashes when I get email, SMS, alerts, etc... but I've noticed that the flashing seems to arbitrarily stop sometimes; without any intervention on my part. I can't find any pattern to this anomaly - sometimes it stops flashing after 5 minutes, sometimes 30 or more. Other times it keeps flashing indefinitely until I check the notifications, which is what I had assumed to be the intended behavior. I'm not running any goofy task killers or notification utilities - just pretty much a stock Hero. Are there any activities that the phone performs that would pre-empt or interrupt the LED flash notification once it has initiated? Or have I run across yet another firmware bug?
