Control problem

[LunaMoo]

I tried to set buttons both with clearing defaults and without doing it - nothing. Is it the only possible solution?

You tried clearing all or restoring defaults? I ment the first one, then setting just gamepad and nothing else manually, but maybe I worded it badly.

I can't imagine in what situation having just one controls mapped activating more at once unless you're intentionaly using some third party software or your gamepad comes with some additional software/drivers/input emulator that try to be smart, but end up doing something wrong.
What does "test analogs" screen I mentioned earlier shows when pressing d-pad?
