Web Object size

I am using a separate player as a menu using a custom skin.  Whenever one of the courses is selected from the menu, a GetURL, self command opens the selected course player.  This works and my client is OK with it, but I would like to eliminate the distraction that occurs as the browser windows close, re-open, and re-size.  

The presentations contain approximately 60 slides in each course, so putting them into one player is not an option.

I have tried using a Web Object to insert the course into the menu player, but the course always shows up at a reduced size in the menu player.

Is there a way to force the inserted player (slide only) to using the full 720x540 area?

Thanks
