File name contains path when opened by dragging the .sng file on open GTUltra window

[demesos]

When GTUltra is running, you can drag .sng files directly onto the app window. However, when you then try to save the file, the full path appears in the filename field (NAME: _ in the save window). In cases where the path exceeds 60 characters, the path string flows over to a second invisible line.

I tested with GTUltra V1.5.4 for Windows.
