I’ve just discovered the issue behind a bug that has plagued me on Windows for a while - apparently GetFolderItem("") returns the path to the parent folder of the application’s folder rather than the location of the app itself. Is this expected, or a bug since one Linux and OS X that call returns the location of the app itself?
[EDIT] Scratch that - my test project default name was too simple and I missed it…
Still digging.
