Captivate 8: Open URL in new window ... but opening in same window

I have several objects that have an action of Open URL or File.  I have set it to open in a new window.   It is working properly when I Preview in Browser.  However  when viewing the published project, which is stored on and being accessed from a server, it is opening in the same window.     I am encountering the same issue in Chrome, IE and Firefox.   Screen shot of properties below.  Any guidance is appreciated. Thanks.
