About 12 days ago my notification bar would not pull down. I rebooted the phone and it started working again. Two days later it stopped working again. I rebooted the phone and still nothing. I powered down the phone and pulled the battery for 5 minutes. Still no go. Today I did a factory reset. With no additional apps loaded, it still would not work. I am able to bring up the bar from Menu->Notifications and it works in landscape. Any ideas?
