Like when I mouse over to the scroll bar on firefox, the mouse doesn't stop at the right edge of the screen, it seems to keep going. Up to a point, the farther I overshoot, the more I have to mouse left before the cursor reappears. It seems like there is an extra inch or two of "imaginary screen" where my cursor can get lost. My program windows, on the other hand, still understand where my screen ends. What's going on?
Other than this, the r7 appears to be working fine.
