Bug details, including step-by-step instructions to reproduce the bug
start game, exit door.
​https://github.com/scummvm/scummvm/blob/master/engines/grim/grim.cpp
default controller layout causes skipped dialog etc
change bindings so that keys are not duplicated in default config
example: "Joy A" = use/talk & skip dialog
causes issues with interaction and talking.

• while this can easily be changed by the user, it might effect some people not aware this is happening.
• also, "Joy Y" is back in the UI, you have to exit the game to set the key otherwise it just goes BACK every time.
