I know this is an old thread but I just wanted to add that I am now having this problem too. I loved Crimson Skies, and just today reinstalled it after not having played it for a few years, and now I'm having the corrupted font issue as described in this thread (the text shows up as rainbow-colored chunky blocks). If it was only in the menus, it might be tolerable, but it also often occurs in the in-game HUD text also. I have a GeForce 8800 GTS, and have tried a couple different driver versions, but they're all fairly recent and thus exhibit the same problem. Has anyone figured anything out in the year since this thread died? TIA....
