Dolphin Wii config problem

[Treybeast]

I'm trying to change the control setting for the emulated Wii controller with nunchuck, but I can't input the buttons for anything in the nunchuck setting by clicking normally. When i do, it says [Waiting] and it never stops saying that even if i input a button and i can't cancel out of it or close out of the settings box forcing me to shut down dolphin. If I Right click and try it like that, i end up with this error message

Clicking "yes" crashes Dolphin, clicking "No" or "Cancel" makes me unable to do anything.
