Not sure if this is a bug, but I noticed that after working in the newest version of VZ for a few weeks that I'm having to scroll down in order to log in, and such. I've attached two screenshots, one of my newest 5.1 VZ and one of my older 5.0 VZ which doesn't have the UI Freespace issue.
The first image is VZ 5.1
The second image is VZ 5.0
