After a complex render is completed in Poser 5, it's often hard to "break" the image so that you can return to the controls, and continue tweaking. I usually click the mouse on the material room, and then go back to the Poser room, but it sometimes takes a long time for the rendered image to "un-freeze." Has anybody figured out a faster way to deal with this?

i wouldn't say faster, it seems it's gonna hold on to that preview till it just decides to let it go. but i click the cartoon shade node and then back to whatever node i'm in. it still takes forever...

I don't think there is a faster way to do that. Based on my own observations, how long it takes depends on how much is in the scene. Only a few low to medium res items and it will take a second or so, but the more high res items you have, the longer it can take.

I have the same problem and clicking around or on the window doesn't help me. I figured out that if I go to "Edit" and "undo change" and then click the window again, that nothing is really undone, but it returns my ability to use the controls

Never had that trouble. I just save or close the render window and there's the preview screen right behind it. I tend to accept that Poser is going to become sluggish when I put a lot of things in a scene, which is one of the reasons why I tend to break my scenes into pieces nowadys.

Agree, Sam. I always render to a separate window just because it is such a pain to break out of the "preview" mode. Plus it is easier to save if I do like it.
