Scroll panes + window resizing

good day, id like to place images and buttons on a scroll pane but i havent a lcue how to use the scroll pane component, can you help?

also… how can i make it so that, when a user clicks on the link from my html index page to enter my site, the site opens to the exact size of the movie and even when maximised only displays the movie and not the surrounding crap, like resizing it as necessary, obviously constraining the dimensions?
if anyone could help this’d be great as im a novice.

thanks oliver

ps why cant i make the very simple preloaders work??? didnt think i was that dumb!?!
