Note: Please only use Microsoft's Internet Explorer Browser when working with documents in this site... Some of the required functionality such as "Check Out/Check In" prompts and open/edit/save on the cloud or server version are not part of the default install for most browsers other than Microsoft's IE. When using browsers other than IE you will most likely be opening, editing and saving non-sever copyies of the document that have been downloaded to your machine. There will be no Prompts reminding you to check back in the document and your edits will only be saved to the copy on your machine not the server.
If you are using Microsoft's IE and are having Check In/Out problems try deleting your browser history and temporary internet files from IE Tools->Internet Options->Delete.
