I don't know if it is a bug or not, but when you're playing LFS in windowed mode, it's annoying to control the car with a mouse. When you clip your mouse to the window, it's OK, it doesn't go further than the window, but then if you're pulling on accellerator (usually it is left mouse button) you accidentally resize your window (mouse picks border of the window and voila). It's not the most important thing, but if/when you have everything done, can you please look at that?
