We just upgraded to WPTools 6.0.7 (information in components are not updated, states this is 6.0.1). A client (not our idea) placed graphics in the document header and footer. The graphic width is wider that the area available within the margins and now the graphic is right aligned (almost out of view). If we adjust the size and save, the problem is fixed - but this is a problem within +1000 documents.
I suspect this an error I can address to you.
If you need I can supply a document.
