Not constantly, no. I much prefer that it disappears and you can bring it back with a touch, but that's just me. The main problem is apps that don't allow that, meaning you have to lock the phone/hit start to check.|
Incidentally, what I do in IE is drag the app bar up just a tiny bit to invoke the top bar and then just let it drop back down.
