In the new version of Bluebeam the navigation bar tends to move dependent on the page scale. This is really annoying when scrolling through large pdfs and end up on the last page rather than the next page. If the scale on the page is set it reads on the status bar on the bottom and the navigation bar is slid over just far enough that if you are clicking away you will hit the last page button. Seems as though this could be an easy fix with there being plenty of room at the bottom.
