I have a problem in Dreamweaver

Hello,
I created a flash header for our fire dept with flamming text centered on the page I went to insert it into DWcs4 and all went well but when I tried to create a new line to insert other items it wouldn't let me return to left alignment without moving the flash swf. ( header), I tried line <br>, and div tags <div> but nothing worked I cant seperate from the header. Any ideas thanks.
