I can't set the 'Music Root' folder to the correct shared root folder in the NAS drive, so rather than using the Library, I simply use the 'Explorer' button.
This has been solved ... and IIRC longer ago than the latest version. Maybe you don't use the latest version (0.9y8-c) ? Or otherwise it will be in 0.9z.
Btw ... with "shared root folder", I take it that you mean a "share name" ? like \\St01\drive_c (st01)\WavTest\ in my case.
If so, notice that you can assign a drive letter to that ... See below at the mouse pointer, which says "Make network Connection". But I guess you knew that.
