Problem with flash

Hello,

I’m a long time WP user and had never had problems.

But now i want to use flash in a post and WP suppress the closing object tag.

Firefox doesn’t mind but safari do
I can correct in phpmyadmin but it’s a real hassle.

Is there a way to ask WP “don’t touch post text from here to here” ?
