I'm sorry if this is a repeat and if you guys are already aware of it, but I have dual monitors, with my secondary to the right of the primary.  If I try to scroll with the mouse to the right, it just moves onto the other monitor and doesn't scroll.  It's not game breaking, since I can still use the arrow keys, but it is a bit of an annoyance because if I click while the mouse key is on the other monitor, it'll minimize the game (which is even more of an issue right now since the game doesn't recover from that sort of thing).
