I have installed 11.10 on 3 Toshiba computers. LibreOffice Calc loses Maximize, Minimize, Close, and file name at the top left corner when I open an existing file on all three computers.
Sometimes it shows File, Edit, View, Go, Bookmarks and Help with no buttons above the drop down menus for Calc.
I have had it happen in Writer as well. If I open a new Calc document from the Launcher and then use the drop down menu to locate an existing file I get all of the buttons and file name. Are there any fixes?
