btw, you really should try to use more descriptive subject lines.  for some
tips, see:

    http://catb.org/~esr/faqs/smart-questions.html#bespecific

most notably:

    "... imagine looking at the index of an archive of questions, with just the
    subject lines showing. Make your subject line reflect your question well
    enough that the next guy searching the archive with a question similar to
    yours will be able to follow the thread to an answer rather than posting
    the question again."
