I'm having this exact same issue on 1.0.2 on OS X since I used it with my PS4 Dualshock 4 controller. The controller thing is probably the issue, it didn't exist in 0.90, I had 1.0.0 for just a day and didn't use a controller with it and never had 1.0.1 installed. 1.0.2 didn't start resetting the settings like described by OP until I noticed controller settings had disappeared since I tweaked them in 0.90 and set them again.
