[xwiki-users] XWiki Workspaces 1.2 probable visualization problem

Hi, I downloaded and successfully installed xwiki-workspaces-installer-windows-1.2-milestone-1.exe, for Windows. Going into the "Administration" tab (XWiki Workspaces Admnistration - http://localhost:8080/xwiki/bin/admin/XWiki/XWikiPreferences ), I see: General, Workspaces, Users, Groups. Nothing about "Import" and "Export", neither with Internet Explorer nor with Firefox. How come? "Import" and "Export" are not available or is it a visualization problem? Thank you Carmelo
