Yosemite, late 2008 MacBook Pro, Xee Version 3.5 (37)

At some point during recent upgrades full screen mode seems to have broken a bit.

There's always the dock's worth of blank space on the bottom and the menu bar and window title bar's worth of blank space on the top. With my settings they're black, so not visually distracting, but it'd be nice to be able to get the image to fill the entire screen again. No matter what I do, even manually zooming, those two black bars always remain on top and bottom of the screen.
