#wait(no_sleep = false) ⇒ Object

This is Watir’s overriden wait method, which is used in many places for deciding if browser is ready or not. We have to patch one line in it to work properly when file save as dialog has been displayed. For some reason READYSTATE (4) property value will be READYSTATE_INTERACTIVE (3) after file has been downloaded and not 4, thus wait will stay blocking. read more about IE READYSTATE property: msdn.microsoft.com/en-us/library/aa768362(VS.85).aspx
