Keboard only works after a button is clicked

I have mapped a PS4 controller to some keyboard buttons, this works fine in a normal Wpf solution.

But in milestone the keyboard keys does not register until i have clicked a button in my view. If i change the active view, I have to click a button again to enable the keyboard keys.

I am using the KeyDown event. Seems like the view isnt selected until i push a button. Any tips?

I am very sorry I overlooked this question for a long time. Can you please tell me if you still have the same issue?

I am not working on this project anymore. This problem is the same as this one:

ViewItemWpfUserControl doesnt register Keyboard inputs (milestonesys.com)

It got answered, so no worries.
