When I'm using the XMMS on FC5(kernel updated to latest), it didn't minimize.
But just flashed once.
Tried several times, all app windows had lost their window borders.
There are no minimize, maximize and close buttons. There's no launched items
in taskbar(panel) eigher. So I returned to FC4. My desktop session is GNOME.
