How to insert a border for a flash movie?
What do you mean by a border?
You could place the swf inside a cell of a table, in the html, and then set the border on that cell to 1pxl.
You could also, in Flash, create a blank layer, above the rest, and place a hand crafted border in it. I guess you would do that by placing a square of fill on the stage. Using the align panel you can quickly center and size it to equal the stage dimensions. Then place another section of square fill in the center of the stage, and delselect it. Reselect it and “edit/cut” it out. There wil be a hole left behind.
