Zeno, your problem is completely different from aszahran's one even if it happens in the same place. Your problem must be bound to your video driver (see the FAQ Sweet Home 3D crashes when I want to edit preferences, print, create a photo or create a video. What can I do?), whereas aszahran's one is probably due to a bug I fixed in version 3.3.
aszahran, could you confirm it works for you now?
