I'm using gnome-screenshot under Ubuntu (in Gnome mode) to make a few screenshots to show a friend how to use certain menu options.

When I try to make a screenshot with menus pulled down, these menus are not shown in the resulting PNG file.

Yes I know, most likely some acceleration in the monitor driver maps them in from some other memory location.

However, the Gnome screenshot app should be able to know what "graphic" is supposed to be there.

Did I miss something? Some magic option? Or is there another screenshot application that can handle this situations?
