Still no cue ? Same issue here with Fusion 7.
Fusion 8 beta is working fine though but meh...beta...so it crashes a lot when using some particular nodes.
EDIT = I just found where the problem comes from, it seems the graphic card is responsible. When I lauch Fusion using Nvidia (Geforce 630M) I have the same problem but it's working fine when I launch it using the Intel card.
