i wrote the same report yesterday on steam, but no reaction… so here again:
Today i installed Train Fever successfully and i was able to play 3-4 hours (i was able to switch back to mac os with cmd+tab). After this i quit the game and steam.
Some hours later i opened steam and started Train Fever again, but some menus in the game were missing. since this i am not able to switch back to mac os with cmd+tab anymore. i tried to run the game several times (every 3rd try i received no black screen), sometimes i was able to enter the game, but after the 10th (?) try i can see only the black screen without entering the main menu, but music is playing.
So i deleted Train Fever (local files in steam) and installed it again. but no changes. i disabled steam overlay in the game. but no changes. i tried this several times… at the end i deleted and installed steam, but no changes.

Any Ideas?
Is there an error-logfile? if yes: where is it located?
