Mathcad 3.0 I am trying to set the width of the header independent of the width of the body of the document. Is this possible? It appears the header size is dependent upon the margin size. If the margin size is set to narrow, the header is very short and appears not to be able to be adjusted. What I would like to do is set the document body for narrow margins with approximately 15 lines of text capability in the header. Is this possible?
