repositioning flash in opera

[nostef]

I am trying to hide a flash movie when a user clicks a button.

Since using display: none would cause all browsers to refresh the movie, I used negative margins.

This is the code:

function special_hide(value) {
$(value).style.margin = '0 0 0 -5000px';
$(value).height = '1px';
}

function special_show(value) {
$(value).style.margin = '1px';
$(value).height = null;
}

It seems to be working in Firefox and IE, but not in Opera. While the div containing the flash is hidden, the flash movie doesn't move.
