I had some problems getting it to work under the latest SL release (5.5) and
the author, Rudy Wortel, sent me the source file. He didn't say I could give
it to anyone else, so I can't offer it. I may be able to give out an
executable, but I'd have to ask about that. Let him or me know if you have
any problems with what is on his Web site above.
