I've experienced this bug some. I could never deliberately reproduce even though I tried for about an hour one night. I mostly use the remote but I've noticed that it happened more when I just wanted a small volume adjustment and I pushed the button in and let go very quickly. Since Beta10a I have not experienced and problems with my unit.
