      Probably, that was due to a syntax change from previous Regex Engine introduced with NT 5.0.

      The What's-new-file for v.5.0 explained:

      "There are significant differences compared to the previous regex syntax used in earlier versions of NoteTab. (...) \n for newline (hex 0A); before it was hex 0D 0A. Replace \n with \r\n."

      One should thoroughly note the meaning of '\R' which was introduced with NT 5.5:

      "Updated the regular expressions engine to the latest release, which is based on PCRE 7.4. The \R newline sequence now matches either CRNL, or a lone CR, or a lone LF."

      Furthermore, it doesn't work in Character Classes and in substring replacements.

      For more details, see Sheri, message #17391, and the whole topic.
