Can't click on the very sides of the map.

If the cursor is on the side it changes to the scrolling one (<< or >>) even on the end of the map, and left clicking for selection and right clicking doesn't work. Maybe the map needs to be narrow to show this behaviour.

Good point; this has now been fixed in Andrettin/Wyrmgus@2f46ff7

I made it so the mouse scroll arrow no longer appears if the edge of the map has been reached.
