Wow, thank you for the quick replies.
I am running my computer at a resolution of 1280x800. The game offers me two resolutions: 1024x768 and 1280x800. Naturally, I have selected 1280x800.
However, the game still appears to be stretched out of proportion. For instance, on the main menu page, the planet in the background doesn't look anywhere near spherical. I know that most planets *are* stretched horizontally to a certain extent, but this seems to go beyond that. Also, the leaders' portraits in the trade screen seem radically stretched.
I suppose I could be mistaken, and this is all just in my head. If it is, I apologize.
However, I have also noticed that whether I run the game in "fullscreen" or "windowed" mode, there is absolutely no difference. I expected the windowed mode to run in, well, a window. You know, with the minimize, resize, and close buttons in the top-right. Or is "windowed" mode something else entirely?
Thank you very much for the support.
