Laurent, start slowly. Do 1. all the tutorials from the user guide of Vue 4 2. Do the tutorials from Mover 4 (twice or even three times with different scenes, to understand) 3. Do Phoul's tutorial Write to e-on if you think it is really a bug (I don't think so)or an incompatibility with your system (always possible). To write to e-on is also important for the team there, because if ever you have a special problem, they need to know about it. Be a nice guy, smile (even if I understand you don't want to smile at all at this moment). And don't distroy your Mover package in throwing it out the window (or send me your address, I will find somebody who will pick it up in the street:-)) Guitta
