I have one user who has had an odd thing happen with her autosignature several times recently. She composes an email (she has her autosignature automatically inserted in every email she creates), sends it, then notices (either by the recipient's reply or by looking in her sent items) that her autosignature appears both above AND below the text of the message she's sending. Before she hit send, the autosig only appeared below her text (like it should). She does not use Word as her email editor. It happens in Plain Text messages as well as Rich Text.

Has anyone else seen this? Any suggestions?
