I'm just guessing, but could it be that the "incomplete images" you get (unless you ray-trace) are not caused by overlapping windows but rather by the PyMOL progess bar? In normal operation (without ray) you may not see the progress bar at all, but perhaps it is there when you generate frames for the movie? AFAIR I get a separate movie progress bar (on the screen) when I render PyMOL movies. Kind Regards, ./ Kristoffer
