Small bug that affects a minority of players that use the keypad. When you attempt to bind kp_enter it instead binds enter.
To reproduce
1. enter settings,
2.bind kp_enter to jump
3.Notice that enter shows as bound not kp_enter
3. go in game hit kp_enter and observe no action
4. Hit enter Key and observe jump
Small one line of code needs to be fixed, unless there is a manual bind workaround from the console. Not sure how to access console in brink or what the bind syntax would be.
