Window menu for LibreOffice Writer is locked under Unity global menu bar.
If I go in System Settings → Appearance → Behavior and I checked "Show the menu for a window in the window's title bar" then no menu is visible for LibreOffice Writer. Also the LibreOffice Writer's window cannot be dragged with mouse from the global menu.
What should I do to solve these problems: unlock the office menu (to have visible minimize, maximize and close buttons) and to be able to drag the window? Thank you.
