Whenever I try to alter the controls, it gives me some line of nonsense about a maximum of 10 axis/buttons per device and refuses to save changes. It even does this if I attempt to hit "Save" WITHOUT altering anything! It does this no matter what combination of controllers I have plugged in when I start it (even just the mouse and keyboard with nothing else).
I've normally got an Apple Pro USB mouse, Apple USB keyboard, Macally iShock gamepad, Interact Hammerhead FX gamepad, Logitech Extreme 3D stick, Logitech Wingman GP wheel/pedals, and a Griffin iMate ADB-USB adapter (for my Apple Extended II keyboard (the lord of all keyboards, bow down to it and its one true successor!), video projector, and Wacom UD6x8 tablet) hooked up.
If anyone knows why the X2 demo won't let me reconfigure my controls, I'd be really grateful.
