What is the best way to use PPTWebBrowser?

PPTWebBrowser > Support Help
PPTWebBrowser loads your web page full screen as soon as the slide is loaded. When you are editing your presentation, it may look like nothing was added but actually everything is behind the scenes. 
 
For the best results.. 
Add a new blank slide to your presentation for when you want the web page to load.
 
Set the background color of the slide to black. 
Insert your web page with PPTWebBrowser.
Set a transition on the slide and set it to 1 second.
 
When the browser is closed, PowerPoint will automatically resume and advance to the next slide for you.
