Edit: some more info. I am running the OS X version, with a Power PC processor rather than an Intel processor, so that may be why. After playing the game further, the buttons seem to appear occasionally, usually when info text appears or when there is a background image. Also of note is the failure of the satellite image to load on the main screen.
Edit2: I've uploaded some screenshots to better illustrate the problem.


This is a minor issue, quite honestly, as it doesn't really make the game unplayable. If I mouse over buttons, the descriptions still show up. However, while I do appreciate the fact that I'm memorizing the menus and hotkeys, albeit it by necessity, it's still annoying. It should be of note that from time to time the images DO display properly, but only for brief moments (for example, in the design menu, if I mouse over a part long enough for a name to appear, the picture will sometimes appear on it as well as other items).
