blogging and scraping

I used to close some browsers by following code:

puts “to close a certain previous browser”
Watir::IE.attach(:title, /google/).close
puts “to close a certain previous browser”
Watir::IE.attach(:title, /Internet/).close
puts “to close a certain previous browser”
Watir::IE.attach(:title, /Internet/).close

but when 2 or more watir programs run together, they stalled there. I don’t know the reason, so I tried the following code which worked ok:

sleep 1
puts “to close all the other browsers”
ie77.close_others
sleep 1
puts “to close current browser”
ie77.close
