No it is not that

It is possible that you were working on the Diagram Editor for over 30 mintues in which your work may be lost. You should always be sure to save your work after 30 minutes or else the content may be lost. Then once you have saved it you can go back in and continue your work in the Diagram Editor.

Thanks. but how do I save it? "save and preview"?
Sometimes I post some games w/ the "insert diagrams" tool and after I do all the hard work of posting and annotating a complete game then I click "submit new forum topic" and there is nothing. It is very frustating can anyone help?
