In the Zune app, when you're at the main page, to the right there is the history of music which has been played. Upon a clean reboot, when you swipe left to pivot right, the history shows itself just fine. However, there are times when I'll swipe, and it'll skip the first two boxes of history, the two on the left, and you'll have to slowly, and I mean slowly, swipe to get access to those two boxes. I cannot pinpoint what's causing this, and it started after my NoDo update. I'm thinking two things here, either just a plain bug when music is played, or my bigger guess, when G-Alarm goes off, it causes this somehow, until I do a soft reset. G-Alarm is the only third party app I have that access my music, so I'm leaning more towards it, but I just want to get more information from you guys.
