I have a recently installed Z140, I know this is not a Z140 forum but I thought you folks here would better know how to deal with my issue since you most likely use the apps the most. The issue I am having is for some reason a menu on the right side of my screen shows appeared and I cant for the life of me figure out how to remove it, It wasnt there in the beginning but now it is, the problem is it reduces the size of the app display and leaves a boarders on top and the image on the screen isnt as good. Below is a pic of what Im talking about. Thanks in advance for any assistance you may provide.

Have you tried to slide from "in" to "out" of the screen? Sorry for my English, I'm Italian.

Yes, I even did a factory reset and it's still there..
