Additional mouse buttons still not work, no matter what I do. It works properly with other games. i think it's just a bag. How soon it will be fixed that is the question?

I have a problem with in game keyboard shortcuts binding. I want to use additional mouse buttons of my Logitech MX Revolution, but can't rearrange keyboard shortcuts for this. Additional mouse buttons don't work in game. i have no idea what options i should set in Setpoint x 64 program, to make it works.
