Hi Natasha and Ora - there are a couple of tricks to making the presentation look like it is full screen. -All are done in the player properties settings.
1. In the player settings turn off all of the features i.e., title, menu, resources, seekbar etc.
2. While on the Player Properties screen select Colors and Effects and then click the Show advanced color editing link. This s were you can make the player border and background transparent. Under Edit item, select Base and set the transparency for Main border, main background and slide background to 100%.
3. In Jeff's example, he made the Page background the same color as the background on his slides. The page background sets the color of the story.html page that is created when you publish your course.
4. Still in the Slide properties, click the Other icon and set the Player size to Scale Player to fill browser window.
Oh yes and there is one other thing - on your actual slides you have to turn off the next and prev buttons (you can't do this in the player settings for some reason).
I think this should do what you want.
