I’ve had no problem with this program with windows 2000 and xp. However  
I bought a computer and vista comes with it.

With Ruby 1.8.6-i386-mswin I get the following error:

require ‘net/ftp’

ftp = Net::FTP.new(‘[ftp.nwlagardener.org](http://ftp.nwlagardener.org)’)  
ftp.login(“nwlagard”,“\*\*\*\*\*\*\*”)

p ftp.status

ftp.chdir(‘web’)  
p “dir changed”  
p “------------”  
files = ftp.list  
files.each {|x| p x}  
ftp.gettextfile(‘cis.html’,‘cis.html’)

ftp.close
