Hi Kurt!

Many thanks for your efforts on this early sunday morning :)
Junior's error is a known one (same a Tao?), I'm not a programmer but it's
something technical I believe B-)

Have to finish my second cup of coffee, wake-up some more...and post my
PawnRace tourney results :)

Kindest regards,
Rick

PS. Don't we just love politics... (Go Baron!)
