I've had a problem with ALT+Tab for a few weeks. If I press that and I want to go back to Multiplayer, it freezes or crashed. This only happens in Multiplayer. Verifying Files of ETS2 via Steam doesn't work. Administrator mode doesn't work. Reinstalling ETS2 and TruckersMP also doesn't work. Video cards are up-to-date. I have been playing Multiplayer with ALT+Tab for years. Does anyone have a solution?
