Display This page Too Tall for Screen

Data Tab; Tuning box checked; Double Click to change items. I cannot see items near the bottom of "Display This " window on the screen. Drag arrows to resize don’t work. Right Click; Size does not work. The only option at the top of the “Display This” window is close.

I’m trying to uncheck the Roll item and I can’t get down to it?

A Mission Planner issue then not Arducopter 4.1?
