some games can use plugins using a d3d9.dll in mainfolder of the game. In combination with Action! the game crashes, without Action running in background, the game works perfect with the dll. Otherwise Action works if i delete the d3d9.dll from Mainfolder.
The games support multiple d3d9.dll´s renaming them to d3d9_2.dll, d3d9_3.dll and so on. So maybe Action should check if there is another .dll and adapt to the situation. But i don´t no how the program works and i am not a programmer...

For more Details or some Test i am available.
