Column browser lists reset

[cryptus939]

Keep running into an occasional problem, where the lists of Artists, Albums etc. in the column browsers will reset to only show the first item in the list. To regain the full list I have to click on All (x items), whereupon all the items reappear correctly. Seems to happen either on the next song playing, or exactly every 5 minutes. Gets very frustrating when I'm trying to look through specific artists. Running MMW 4.1.28.1905.
