--- Comment #44 from fouf other@jarmash.com --- I have found a temporary solution for those who do not want to apply a patch. On the top right, hit one of the buttons (such as the objective one that is a bunch of checkmarks in boxes, or the diplomacy tab), and while it is up, just press all the arrow keys and go back. It should un-stick the scrolling. You can do this to reset it anytime it happens.
Still very annoying, but at least it doesn't ruin the whole game.
