Hotbar Disappearing Glitch

I have expirienced a couple of bugs/glitches, one being the hotbar disappearing. Yeah I was playing hunger games on a server, and my hotbar disappeared. Another glitch I found in the beta 1.1 is that the last slot (all the way to the right) could sometimes drop the item (when you hold the slot) even though I am not holding the slot. Please fix these bugs, I want to play minecraft pe smoothly.
