I apologize if this has already been discussed in another thread. This is the biggest thing that has been bothering me about the new dashboard. At the top of the PLAY, WATCH etc tabs is a very small dead zone for clicking. If you put your mouse at the highest point on the screen, you cannot click any of the tabs, but you can highlight some of them. I'm not sure if this is a problem with the resolution I'm running, so for the record I'm running at 1920x1080.

Also, overall, I like the new dashboard. Obviously, like any major change it required work, but it seems like a more flexible and usable interface than the old one.
