I have a saved profile and have had very few resetting problems. I usually restart the driver if it does reset. I am using a 4000 FLX 3DxWare 4.2.7, FW 2.43

These are settings I've had for a long time, and they could probably be revisited. I really don't use all of the buttons, usually just Mate, Left Ctrl, Left Shift, and Esc. I think I have just found motivation to work Enter into here somewhere.
