in this case, I fixed this problem by 

ie.disable_checker(Watir::NAVIGATION_CHECKER) 

but in the 1158 version, I can't do that. 
( I searched the code and I do below

require 'watir/contrib/page_checker' 
ie.disable_checker(PageCheckers::NAVIGATION_CHECKER)

but it isn't solved )

How can I solve this problem?

Thank you.
