keyboard wont go away

At first I felt this was an "ok" app for the money with some useful reference information on the elements...but then I activated the keyboard and it wont go away (so I cant access the options at the bottom of the screen). Once this bug is fixed (assuming it gets fixed), then it would be a significantly better app, but right now I cant recommend spending the 99 cents on it.
