In the interntet program that uses strings on page 113, the program works just fine if I am using windows 98. On another computer, the one I use all the time running windows 2000 professional , the program crashes with the following message. /cygdrive/c/RUBY/lib/ruby/1.6/net/protocal.rb"445 in 'new' invalid argument "connect(2)" (ERRNO::EINVAL) from p113.rb: 23 in 'join' from p113.rb 23 from p113.rb:23 in 'each' from p113.rb.23 Any ideas for a fix?
