Vertical compilation

When compiled into .rtf or .doc the resulting document shows a vertical writing style: each line shows one symbol and then breaks off, e.g. a 10-letter word needs ten lines. I am quite sure that this is unusual. Preview, .pdf and .odt on the contrary appear in a conventional manner. I don’t have Microsoft Word installed but OpenOffice, so I suppose that there may be a connection between this state of affairs and the problem (I don’t know whether the compilator depends on the external editor).

Use of the .rtf-compilation is under current circumstances necessary because I need my footnotes at the bottom of the page instead of at the end of the document; therefore I am hoping for a solution. Thanks in advance for a reaction.
