Enabling second controller freezes Bigbox

[Carl Paulino]

7.1, win 10 x64 latest xbox one wireless controllers connected with usb wireless adapter. all the latest controller firmware and drivers as of 12/24/16. Bigbox enabled for one controller and has controller automation enabled too. Enable one controller by pressing guide button so it syncs to wireless adapter. Launch BB and everything works fine. Enable second controller and BB totally freezes and cannot come out of it. Have to kill with task manager. Now both controllers are enabled and active. Launch BB and the gui window will never appear. bigbox.exe will be running in task manager but with no gui probably because it's totally frozen. I can reproduce this every time. I found that if I want to use both of these controllers, I have to have the BB setting enabled for ALL controllers and then things work ok. I do not know which version this bug started in, because I never enabled both controllers with BB open until now. Maybe this would also happen just using two xbox360 controllers as well. I don't really think it's limited to just xbox one controllers, but i guess it could be.
