Hi Christopher, this sounds to me as the scale of your display could be set better. I mean, Animation Paper thinks it is on a very hires but small display, so the interface and icons are made large and the window is at its minimum. This means it can’t be resized to a smaller size and some of the window sticks outside your screen area. Does that sound right?
Fix this, by adjusting the below setting in Windows to something less, like 100%:
