For some reason, my buttons for live settings and turn signals have stopped working. Once before, I mapped those buttons to other controls accidentally, but now they won't work. There aren't any settings for those buttons either. It really sucks.
What wheel? If you use the Logitech profiler for assigning buttons, just start LFS from there using its profile... Usually, the buttons don't get assigned when the profiler doesn't understand what executable is running for LFS... I lose my button maps when I run LFSGhost to start LFS. Or when I run LFS through a batchfile it messes things up. So I usually start LFS from the profiler itself, and set LFS as the default settings in the profiler just so it works 99% of the time.
