eDrawings sometimes opens an earlier version of drawing

We seem to have an occasional slddrw file that, when openedin eDrawings, opens an earlier version of the drawing. That sameslddrw opens fine in SW.

Since the option to save eDrawings data is gone in SW2006, I'm notsure how to get the eDrawings data to update. Does anyone know whatmight be causing this problem?

We are using eDrawings 2006 and eDrawings 2007 (I have them bothinstalled) Both versions open an older version of the drawing.
