I have often died as an alien when i try to evolve, but i can for some reason or another (like humans to close), and that stupid popup window comes up. Then i have to click around to hit the stupid little OK button before i can get out of the way. Also the popups you get when you try to build in the wrong place.
These could instead be replaced with text that appears on screen (without a window) and fades after a few secs.
