Why are there borders around my pages!?

I’m trying to make a full flash website using MX, and I cannot for the life of me figure out how to get rid of the “border” that appears around each page. For instance, I have an index of a specified size that when you click on one of the projects another window pops up to a slide show of that project. Both the index page and the project page have this border around them that are the color of the background (from the Document Setup option). They appear about 1/4" wide or so. Anyone know how to help me?

And if anyone is feeling really generous…how do I make a page that pops up and opens full screen (detects what size screen the user has). Thanks!
