Issue on vAmiga saving session

[Gri-grid-07]

Hi to all,
I downloaded Virtual C64, then I downloaded vAmiga and I legally bought the Kickstart ROMs on Amiga Forever.
I noticed that in vAmiga the function Machine -> Save/Save As... does not work well: the title of the vAmiga window always shows "Untitled" and not the name of the saved file.
Also I can’t restore a saved session with files .vAmiga as I do with Virtual C64 with the saved files .vc64.
Maybe I’m doing something wrong? Maybe it’s the disk (virtually) inserted in Df0?
Thank you all very much.
