I will admit to playing Symphony with just my touch pad (mouse died a terrible death on release night), and its FINE nothing wrong on that front, but I've noticed after only about 3 or so songs, my cursor won't go to the edge of the left side on the Artist Filter page. So If I wanted to play songs by an artist who happens to have three letters to their name (ie: MAA), I can't get to it to select.

The problem goes away during game play, but if I keep ignoring it it gets to the point I can't even hit the Filter options on either end of the screen too. I have to quit out and restart to "fix" it.
