Media box works with folder icon (on the main menu & 1st)> browse. Then crazy little icons like the mini-orb on file name (ditto weird mini triangles next to non working major icons) to make it play. Stopped refresh search at start in prefs. Oh yeah and lookout for normal, repeat, shuffle etc, on the 'main bottom menu' of media chooser on the right mini panel. Mad. If you come back to it & controls & display's wacked out, try quiting but cancel to refresh. I guess one gets used to it's strange back icons too. Will use it for major sessions but for quick jobs, kilikali. Thanks all.

Will check Canola next.
