I have an EDTracker and in bet7b it works well selecting the "Joystick" option.
However, if I select the "Tracking" option (or any other option beside "Joystick"), there's something wrong: as soon as I quit the settings page and go back to it, the "Joystick" option is once again selected.

Actually there seem to be more wrong stuff: it seems to work only in "Tracking" mode, even if the setting says "Joystick". If I stop opentrack, freelook no longer works (which is OK for "Tracking" but not OK for "Joystick"),
