No I have not saved my controls config in the Blackshark.lua or other files.
Now, I have installed DCS trice, and same problem. Then I go to in DCS/options/controls, no keys are selected at all. I can programme single keys, but then I try to select a combination like shift+key, Alt+key and CTRL+key, Nothing happen.
My joystick (Saitek AV8R-01) works fine, also its buttons works fine, but again, if I choice a combination like ALT+Joystick button 3, It´s showing red in the controls menu, and then I can't save my profile. Then I tried to select a combination with to keys (shift+key and so) nothing happened, What I mean is no error occour, then I try to save the profile, just because nothing is selected.
I have saved a control config.lua file, before I changed to Win7, and I'm 100% sure it worked perfect. Then I loaded this file in my new installed DCS in Win7, my joystick and all its buttons work perfect, also the buttons I have created by my self, but again, all my keyboard key selections are gone.
I have installed the newest software/drivers to both my keyboard and my joystick.
