This is a minor bug, but I figured I would report it nonetheless.
When you click on the minimap righ above the "turn" button, it will actually click the turn button. This only bothers you really on Gigantic maps, since you may have a planet or star base very close to the turn button on the mini-map. You would have to click away from the starbase/planet, and then scroll to it. (Especially annoying for starbases, since you have to manually send all of the constructors to it, I can't tell you how many times I wasted turns trying to update a starbase - only to have my turn end when I clicked on the minimap.)
