I just got diplomacy and am on my second game. the problem i am having in the second (but not first) game is that when i either use the arrows to scroll or move the mouse to the edges of the screen it acts funny. left and right act normally (relative to your view) but up and down seem to be absolute and changing occasionally. when i move the mouse to the top sometimes it will scroll down or to either side. if i orient the screen so that what was scrolling up is at the top it works "normally" but if i orient it any other way the screen still scrolls the same way it was, even if the way it was scrolling is now left.

I have tried restarting the game but that doesn't work. i have not tried it in any other game but it wasn't a problem in my first diplomacy game or ever in entrenchment.
