generic joystick button assignments lock up the sim

While my ch joystick settings remained intact after the update, my generic usb joystick lost all of its settings. I am able to set the axis, but when I try to program the buttons, the sim locks up after the sim recognized an input. From this point on, I cannot get out of the window without closing the sim. The mouse highlights the various fields, but they do not have any effect. I read about recovering the old setting from a video the other day, but I am curious to know if anyone else has this problem. It's a bug that applies to generic joysticks.
