A little after a couple of days: It turns out that while the display is now complete, the program behaves now rather "ticklish" Doing too much of zooming, panning etc with a large model leads to crushes of the graphics driver (the message says explicitly!), the PV prog window becomes completely white and the program does not react any more; has to be killed with the task manager.
So better save as the first action after a lengthy calculation, and only then try everytjing else to investigate the result.
