I am working on a project that needed the visualization of several orbitals of relatively small structures (40-50 atoms). I used to simply copy the visualized orbitals to my documents and life was good. For a while everything was OK, but recently I often get an error message, when I try to copy the content of the window: "Rendering could not be performed for an image strip of size 309 x 576 pixels. This may be a limit of the hardware acceleration graphics driver." What is the problem and how can I avoid this situation? I need the figure of several HOMO, LUMO etc orbitals.
