So far they seem complete. Although the ship design window has a minor overlap on the left side witb some text voxes (easily worked around)
Although honestly i play on a 768 high monitor, and with reduced height... I can still play the game. Some of the buttons though you have to search for. (For example, the missile and turret design buttons normally at the bottom of the research project window, i have to use the ones at the bottoms of the industry window.
1 thing i will mention if you are just starting though, is that the game has a few bugs on windows 7 due to many old .dll files no longer being included. The most annoying of them is that you probably cant use the "system information" window (opened by 'F9' ) among some other minor bugs. (Though I legit cant find a reason to NEED the system info window as yet)
