Some likes the old C4 UI better???? May I ask why? The new UI is more professional looking and it gives you more workspace that the previous version. Windows and tool bars can be undock. You can even place the tool bar icons on top of the working window with no problems. Customed keyboard shortcuts. Use wheelmouse to zoom in and out. Please try it out and very soon you will not want to go back to the C4 UI. I sure wouldn't want to go back to the old MetaCreations style of UI that just waist space. Question did you get C5 or C5Pro...C5Pro has more advance modeling tools takin from Hexagon. Spend a little bit more time on it. Try the new particle system. Later Ringo
