Hi all,i have a problem(i think was already written here,but i can't find it anymore)..when i scroll down,i don't know why but i think randomly,the window become fullscreen...and then comes back to normal...how can i solve it? This is the main problem,then there is something else: 
  
-3 and 4 finger gestures doesn't work(only the one to see running apps) 
-Slow scrolling(Partially solved in chrome with smoothscroll) 
-When scrolling,fingers have to be horizontal to scroll,if they are not,i can't scroll (i don't know if it is clear, 8 <-won't scroll(imagine they are 2 fingers) ∞ <-will scroll) 
  
Thanks in advance!
