When I was creating Midi Lanes for stress testing, I fitted the lanes in the window, but I couldn’t scroll down to see more when I exceeded the size of the window. I had to maximize the page to be able to see, and then I saw a whole lot of empty space under the lanes I made, and the ones I wasn’t able to see before maximizing. After Maximizing the page and fitting the new lanes, I could not scroll down or maximize the page anymore.
