> I suspect this happens because sometimes I edit the files on my Linux box and sometimes on my Windows box.
If I remember correctly, RCS (and the earlier SCCS systems) were designed to work with source code (i.e. text files). They determined file changes based on lines added or deletes and had a fixed length internal buffer used to read each line. From what I've read in this discussion, I think the issue is that the '^M' characters may not be seen by RCS as an EOL. If that is the case, RCS will read the whole file as a single line and large files (>65KB) may not be properly handled. Use dos2unix and unix2dos to convert the files and you will probably eliminate the issue. My $0.02 Brian S.
