Seems it does occur most frequently when it is just a selected area that has been modified. When this happens, I walk the recipient through changing his normal.dotx defaults to Arial 10pt, single spacing. Is there a way to correct this without having each end user redefine the normal.dotx?

However, it also occurs to paragraphs and parts of paragraphs that have been formatted using styles. This, I don't have a fix for yet.
