Just updated to 1.01 with diplomacy, and I've hit a weird bug. I can use the up and left cursor keys to scroll the map. but the right/down arrows seem to be tempromental. My home planet is in the bottom right corner of a huge (multi) galaxy, and I don't seem to be able to properly scroll right near my planets but I can mousewheel zoom around, as well as pan as normal.
The only reason I can think for this happening is because the game thinks the edge of the map is in a different place, so won't let me scroll down past that edge? I'm not sure.
