Control T toggles fine. It's the actual BBW window that won't maximize vertically. It fills the screen horizontally fine, but not "up and down." If I put my cursor at the bottom of the screen it shows the arrow as is typical in windows. But it won't let me left-click and drag the bottom down any further. Right now, it leaves about a third of my desktop showing beneath BBW. All other windows and programs operate fine, and can be maximized, etc.
