Not sure how long this has been an issue, but when navigating into the first level of Music folders (Genre, Artists, etc.) in the two skins I use, Aeon MQ7 and Titan, there is no upper tab to click that will let you return to the Main Menu. This is not an issue with Estuary, as you can navigate sideways to the main categories directly from this subfolder.
The reason I point this out is that I’ve also learned that the “back” button on my MS Media remote will not allow you to go back to the Main Menu from this subfolder either. My keyboard “esc” will does work, however.
Very weird…
