After rendering in Poser 4, I return to the unrendered view by clicking the trackball which sometimes takes several attempts. Am I doing this right, or is there another way of doing it or perhaps a keyboard shortcut. Thanks, Tommy.

there is nothing wrong in it, you can also click somewhere in you renderwindow, and that you sometimes have to click more than one time is normal

If you dont already you should try rendering to a separate window, see "render options" in the render menu. It is much quicker at getting back to working on a scene as the scene doesnt have to reset itself. Only annoyance is you have to click a button as it asks if you want to save the render. Deleting objects is where I have to keep bangin` the rodent.

Just click on the surface. Usually that will snap it back to preview.
