Hotbars disappearing, loot window not appearing

[speedycerv]

I have 2 problems, on one account/character Randomly a hotbar will disappear and make a double of itself over another hotbar. If i close the hotbar and reopen, it's ok, but annoying none the less.

for teh second problem, which is more of a bigger deal.. on another account/character they never have the loot window come up. They never roll for loot, so it's seeming like the Auto decline option is stuck. However if I check out this option, it's not checked. Is there a way to reset my ui so that it might resolve these issues?
