Hey there! Just updated my machine and running W8.1 now. Only current issue: Race07 and the like are not starting in window mode (I need this because of modding purpose). Tried the Steam integrity check, deleted the config.ini and started the config tool several times but it seems like during start the game or steam overwrites the configuration - but only the window-mode setting Does anyone have an idea or solution for this? How do I force the game starting in window mode?!
