You can always spot an EA diagram in a document: they have a border around them, with a little extra title box in the top left-hard corner - the one with the flattened corner.
Ever wondered how to get rid of the border in an eaDocX document?
(and also when copying it with the clipboard to any other application)? Look no more!
In EA -Tools - Options - Diagram - Diagram Frame, just un-check the 'On Clipboard Images' to stop the border from appearing.
A word of warning for eaDocX users: if you have empty diagrams which get pulled into an eaDocX document, and the border is switched-off, you'll just get some mysterious whitespace, with a figure number below it. For more information on excluding diagrams, see the Help.
