Windows.
I assume you are referring to the auto up function that randomly stops working? i.e. going up and coming back down like it's hitting a restriction when none is there? Mine does that too. About once a week I have to reset (lower completely and keep holding the down button for 15 secs), then it starts working again for another week or so. I assume its the tracks need to be lubricated as there is nothing in the way of mine. I'm just too lazy to do anything about it. lol
