Moto Droid using K-9 Email app. I often get a notification on the bar that I have 2 emails. When I open the notififation window there isn't anything there and I don't have the "Clear" button.. When I check my mail everything is showing it has been read. closing the notification window I still have the 2 emails showing in the bar. The only way to get rid of it is when something else comes in causing an additional notification. this will give me the clear button and pressing it actually clears the alerts.
