Drag the arrow thing in the box to change the speed. The faster the speed, the faster you'll have to double-click to make it work! Double-click the circle to make it change. If it doesn't change colour, there's either a glitch in the program or the speed setting is too fast. (If you put it at the far end, it's literally impossible. Yes, literally.) Happy double-clicking, -Giantfishy --==/ending transmission\==--
