html FRAMES - looks fine on IE - but the frames "squash" in Firefox/Netscape?

the easiest way to let you know what I mean is probably just give you the URL... http://www.unnaturalhelpers.com/olivv/cinema_pulp/cinema_pulp.html .. It looks fine in IE so far but in Firefox and Netscape the vertical and horizontal scales to the browser window. does any one know how I can prevent this? I would re-do it in tables but the way the 2 .SWF's communicate I'd lose alot of whats cool about it. -thanks- M !! -by the way.... adding height = "400px" width = "400px" into the frame src does not help !! neither does taking off the percentages when I define the collumns and rows... again it looks fine in Internet Explorer but not Netscape and Mozilla type browsers.
