IIRC, Stuart Morgan changed window creation to provide the X property
_NET_WM_STATE_FULLSCREEN, which indicates to the app that it's a
fullscreen app, now that we're using Qt4 (which--unlike Qt3--supports
that X prop).  It may be that fluxbox treats "proper" fullscreen windows
differently, making them always on top.

In Qt3, our "fullscreen" window was just a window the same size as the
screen and with decorations removed (so the WM never knew it was
"fullscreen").  Try checking the box to run mfe in a window and see if
placement rules change that way.
