I'm using ScaleRichViewEdit in a project that must export RTF files, so that's the standard file format I'm using. Inside my software everything works fine. But when I open the RTF files with Microsoft Word the last lines of each pages changes to the next one and so. I checked the page layout and it is identical on both softwares, i.e., the page layout doesn't seem to be the problem.
Is this a bug or am I dong something wrong?
P.S: the same problem happens with the SrvAction demo available for download.

While page size must be the same as in MS Word, text width and height may be calculated slightly differently.
