Position Page at 0,0 on screen

Hi Clifton,
I am using some js code to create a Skype-like application. This functions quite well but I want add a full screen function. I think I can do this by getting the screen size and resizing the (modified) HTML 5 video object accordingly. The object is displayed in a TB field using pgGotoURL. I can move this field to 0,0 on the page and enlarge it as necessary but how can I move the page to 0,0 in the browser window? I expected to be able to do this using setPageContentPosition but so far I haven't succeeded and the page remains centered. Maybe I'm missing something.
