Yea I have the same problem with either my Xbox 360 wired controller, CH Pro USB pedals or my CH Flight Sim USB yoke. I can program buttons in all day but whenever i try to change the axis bindings they don't work at all. The only way I have ever gotten around this issue is to move KSP from the steam app folder and to a flash drive or other folder then start steam and uninstall and reinstall KSP but make a copy of the fresh install and move my mods and save game to the copy. I then play on the the copy directly and can once again change axis bindings without the screen graying out. if the game crashes or I close it i have to make a new copy and do it again. it seems that KSP only likes to bind axes in a fresh install I don't know why. I have even tried with out mods and I still run into the same problem after the binding change. I know they are supported because other games like Microsoft flight sim x steam edition the controls work fine on all three devices. any help would be much appreciated. i have run into this problem since 0.90 to 1.0.4 When I have been able to bind the axes it works like a charm but if I reload the game the bindings are no longer there and if I change any other settings I run into the problem of screen resizing and even if started from the launcher the problem still persists. This is so very annoying and I would really like to free up some disk space so I don't have to have two copies of KSP on my computer. no settings are saved even though in the config file they are correct it seems to either not check the config file or is checking a config file in the hard code and glitching out.
