Curious-


	I don't know much about watir but I think you could easily just  
rescue the exceptions that watir throws when the Next link is  
disabled. So run your current program again and look at what kind of  
exception it raises. Then you can rescue that exception and move on  
to the next set of pages:

	I don't know what error you get exactly, lets assume its  
WatirException(i'm sure its not called this but you get the idea)

begin
    ie.link(:text, "Next").click
rescue WatirException
   #code to move to the next set of pages
end
