TotalFinder is not maximized on the screen

(!This is not about the full screen mode!)
TotalFinder is not maximized on the screen. (This is the action when you press the green plus button at the left upper corner of the window).
There is always some small area (either at the top or buttom; AND left or right). I can move the window those couple pixels. But I can’t resize the window to make it bigger to fill the whole area on the screen (except the menu bar, of course).

The window needs to be filling the whole window.
Here is the example where the right and lower parts of the screens are not covered by the screen (I have grey wallpaper, so look carefully :wink: ).

Please install the latest beta, it is fixed there:

darwin, thank you! I’ll try it.
