Hi John!
In order to load another .html page into an already existing instance of IE, you just need to use the reference (green wire - Automation Refnum) for that instance of IE. Then you need to use another Invoke Node to load another URL into the web browser. Refer to the attached picture below for a visual of this.
Secondly, the Title Bar of IE is using the title of the .html document. For example, if you create an .html file in Microsoft Word and save it as a "Web Page," you will see that the Title Bar will say "Title of your file - Microsoft Internet Explorer."
Hope this helps!
