Dear Dota 2 forum

Since 1 week i can't move my "view window" ingame with my mouse. To explain everything a little bit better, i took some screenshots:

As you can see, my mouse is fully working, drivers are up2date and i can use it ingame:

If i try to move my "view window" i have to use WASD or to click on the minimap as you can see here:

It would be so cool if anyone have a soloution.

PS: someone changed my config files and i dosn't know what he did, i already try'd to use the old one and used one of my friends, but this didn't helped me. I also restarted my computer multiple times and reinstalled the game.
