Swf auto-centering in iframe?

hi all,

sorry about the continual questions, but nothing seems to work out the way i want it to at the moment!

when i have a gif in my iframe, it aligns to teh top of the iframe, but when i just replaced it with an swf, the swf is now centered vertically… i can theoretically resize the iframe but i don’t want to do that, i want to work out why the swf is centered when the gif wasn’t.

i’ve just got no idea why the swf would behave differently.
