On a dual-head display, mouse cursor can't move to different display

[Andy Alt]

If 0 A.D. is on my left display, The mouse cursor can't go further than the right edge of the left display. To move it to the 2nd display on the right, I have to switch from full-screen to windowed mode.

I probably only noticed it because on another RTS game I played, when the cursor is *near* the right edge, the map will scroll; when I move the mouse further right to the 2nd display, it will get there, but the map continues to scroll until the map border is reached.

Perhaps the former, not the latter, is desired behavior. *possible* defect.
