Netscape prob

Hi guys!
I’ve got a little problem with Netscape. I have a site that has a .swf in it loads when the user clicks a link on the previous page. It loads full screen and works great in IE. But when I open the page in Netscape, the .swf is really tiny at the top of the screen.
Does anyone know how to resolve this problem? I’ve tried searching the forums but I couldn’t find a good answer.
I’m using the following javascript to maximize the page with the .swf

function fullwin(targeturl){,"","fullscreen")
