Thanks for confirming. I have reported it in Mantis: http://www.ventismedia.com/mantis/view.php?id=7703

Can reproduce that. I guess it is intended behaviour to have "My Documents\My Music" as default location when nothing is selected.
I agree that it can be annoying with large and deep folder structures.

Unless I select a Location subnode or a Media Server, Add/Rescan Folders keeps enabling the My Documents/My Music node despite that I have deselected it. This happens when no folder has been selected by default (ie if I only scanned a Media Server last time).

Tested on skinned 1367 on XP. Can anyone reproduce?

PS. I still really miss the MM3 feature listing all folders selected for search. The current implementation makes it really hard if you have multiple folders selected over multiple drives and machines which might be many levels deep.
