When you have the Results Map zoomed and panned, then use Print/Export (Ctrl-P) the print window captures the wrong area of the map to print. If you zoom/pan to different areas before opening the print window it varies on what it will show in the print window.
the graph window

the Print window

obviously L4 is trying to show a zoomed view of the graph window in the print window, but it is not finding the right area of the graph window when it shows it in the print window.
i also noticed that sometimes after opening the print window that it repositions the graph window to a different location than i had it zoomed/panned to.
Just thought that i would point this out so that you could add it to your list of things to fix in the future.
