When the Apache OpenOffice UI looks old-fashioned (like if it would run on Windows 98 or similar), it is very likely that a specific library is not installed. In a terminal please check if the package is installed. If not you have to add it. After a restart of Apache OpenOffice you should see a much more modern UI.
