When I open Master Slider to work on either of my slides I get just the middle of the page with the top and bottom cut off. I can press f11 to hide the top and bottom browser bars but I still cannot work on the page correctly.

What is causing this please? I’ve tried de-activating other plugins but without any improvement.
