It seems to happen randomly ... but often I try to use the "Save As" command, and the song looses it's .SGU property, and it becomes a PDF, which does not work ... I sure would appreciate any help in understanding how to avoid this process ... I've had a number of songs I'm working on, and I am unable to save them properly under the "Save As" command from the File menu ..

Thank you very much ...

Donnie ...
