Maybe someone can explain what is going on...
I have the same problem, as soon i want to change the deck, Resolume crashes completely. In my case there is nothing else to do than reboot the whole computer.
But now I realized an other way: When it hangs (crashes) I leave it hanging and open up another instance by manually chosing my composition in the "my documents" section. This instance runs absolutely clean, no hanging, no crashing, everything runs beautiful... The crashed instance is kept open the whole time, when I move down to the taskbar it shows the broken instance in gray and the running one in normal colors.
I know, it is not to be supposed this way, but maybe one of you programmers can figure out something on that.
