Help with some learning interactions?

I am trying to add some learning interactions into my project (specifically, memory and millionaire), but the box where I set up the interaction seems to be bigger than my screen.  I can add content to the interactions, but the "OK" button that should be at the bottom is not accessible.  It won't let me grab and move the box upward, and I've tried moving the Windows taskbar out of the way, but it wasn't enough.  Is there a way to slide the box upward, or is there a keyboard shortcut to accept the content?

Thanks,

Sandy
