Pages and Refreshabraille

Braille on Apple Products

I've finally reached a frustration point. When using Pages on an iPhone 5S with the Refreshabraille, the app moves the display to the menu bar after a couple of minutes. The phone has not gone to sleep, or timed out. How can I avoid this happening (it is particularly frustrating when taking notes in a meeting since then you have to try to find where you were, route the curser, and then begin typing) or making a few keystroke correction to the problem so it automatically goes back to the text entry field and to the last character entered. Help appreciated.
