Haven't used Jaikoz in a while; updated today. My problem may be user error, though I think I've RTFM carefully.
Using V3.3.3 on Mac OS 10.5
Select File: Open Folder: <folder name>; "Include Sub Folders... " is checked. Click Open Folder, expecting to load all the files in the subfolders; the folder itself contains no songs - just the subfolders.
Jaikoz reports "0 songs loading from /Volumes/Main/Music/<folder name>.
If I select any of the subfolders, Jaikoz loads the songs in the subfolder.
<folder name> is any folder in the (relocated) iTunes music library (though the problem doesn't appear to be related to iTunes, and I've made no other changes to the standard iTunes configuration).
What am I missing?
