This is, unfortunatly, a rather rare issue with loops. I very rarely encounter it, so it's hard to find them all. I'l look into this one, thanks. Out of interest, what kind of spec is your computer? What kind of FPS are you getting? Which graphical setting?
By controls, if you mean the annoying combination of mouse for the menus and keyboard / gamepad for the gameplay, there's nothing I can do until the menu is replaced. Considering I know nothing about Flash / Scaleform, this is one of the last jobs in the project.
