Are you referring to the icon menu at the top of the screen? I also use the same device on Verizon.
There was a system update that I just downloaded about 2 weeks ago. Go to the phone settings and post the system version and Android version installed in your phone. With that said, my phone shows System version 4.5.621, Android version 2.3.4. I have not experienced the same issue with my Droid X.
If your System and Android versions are the same, I suspect a bad install happened on the phone. Any chance you might have accidentally interrupted the install process?
My Droid X was just updated a day or so ago and now suddenly my notification bar has gone missing. The phone is not rooted and I have not done anything with the phone since I did the update. Also when I restart the phone for a while the notification bar will be there but as soon as it gets a notification the bar disaperas. Why is this suddenly happening? How might I fix this, for someone who mostly a user?
