Error connecting to new window

I am trying to find the best way to connect to a new browser. I have used the following successfully.

browser.attach(:title, "title")

      

        
        
        
      

    

I read on the Watir development group that the preferred way to do this is:

browser.attach(:title=>"title")

      

        
        
        
      

    

This syntax seems to work for all other elements besides the attach method. The error method I am getting is ArgumentError: wrong number of arguments (1 for 2)

.

My tests are working fine, I'm just wondering if the attach method supports both ways to do it.
