Then when I add graphics to the buttons, the option to link is not available.
I do not want to link but in OO the link was set by default and you would uncheck it and it would become an embedded image.
With LibreOffice 4.2 The filename returns and it does appear to load properly on different workstations with different mapping.
THE BIG PROBLEM IS that all my images on 20 or 30 base forms with 5-6 buttons disappear as soon as I edit.
