*Guida:  "15. I can't change the preview window size for a size larger than my screen resolution (1280x1024), you may think it's useless and yea you can render at higher sizes, but a bigger size on preview gives me a better perception of the image,  P6 allows this."

*Were you using SR3 on Poser 6?   I seem to remember reading that one of the Poser 6 upgrades introduced this restriction.

This is not the same as the problem digitell reported, which e-frontier has acknowledged (with fairly red faces, I trust).
