Right now the Game is running to fast. You have to edit the DosBox config file and change cycles=auto to cycles=25000 (approximately...It has been a while).

thanks a lot but it is the same sadly i also tried out 10000 :(

I had the same issue and slowing DOSBox further down helps eventually, but then the whole game is getting slow and that's not worth it. As simply flipping an object is all that you need to access all action spots, you can work around this issue by using short clicks until you see the object's backside. No need for slow turns and thorough investigation. It's not a solution, but good enough to play the game. Just take it as something that comes along with old games on modern systems.
