richtextbox not saving to access?

[INeedSomeSeriousHelp]

When I add a text control and connect it via the DataField, DataMember and DataSource = (DataEnvironment) properties, it saves properly to an access database...but now I would rather use the RichTextBox (more powerful), but when I connect as described above with this RichTextBox, it doesn't save to the database?? But...I can get the RichTextBox to save if I do this:
After adding new text to the RichTextBox, I click on a Grid on the same form and enter new text...this somehow gets the RichTextControl to save?? It's not just saving because I set the focus on another control...have tried that already.

Help please
