title: How to set WATIR focus on new window
body: <p>I'm new to WATIR testing (and do I love it!) and have run into a wall on how to refocus my WATIR script to a newly opened window.. Here's my (simplified) script....</p>
  
  <pre><code>#!/usr/bin/ruby
  require 'rubygems'
  require 'watir-webdriver'
  browser=Watir::Browser.new
  browser.goto("http://0:3050")
  
  browser.text_field(:name,"userkey300203830").set("OKJHNB")
  browser.button(:id, "interview48").click
  
  puts "Expected Result:"
  puts "A successful display of cars"
  
  if browser.window(:title=&gt;"300203830").exists?
     puts " Test passed. New window opened!"
  else
     puts " Test Failed! No window found"
  end
  </code></pre>
  
  <p>It all works right up to the end.  After the key "interview48" is clicked, a new window is opened with the title "300203830". Looks like I find it but I just don't know how to now focus on that window.</p>
