When I start the Steam game (Dirt 3, F1 2010, Grid) using Presentation Viewer, it dissapears, then game starts and everything runs fine. But when I close the game, the Presentation Viewer won't appear again as it does for example in non-Steam rFactor (although Converter says "Game Stopped"). I have Windows 8 x86 and X-Sim 3.0.2.8. In the game profile, I have a path to the game .exe file, and in the parameter field there is Steam Game ID (starting with steam://).
I think that this is a bug because in non-Steam games everything works fine (Presentation Viewer appears again after closing the game).
