Synchronous scrolling between two windows are slow - Firefox

[Jose_49]

Hola!

I have been trying to come up with something interesting. I'd like to synchronous scroll two pages.

This is the script, achieved with jQuery:

$(document).scroll(function(e) {
if($('#dualpage').val()=='Exit Dual Page Mode')
{
$(w.document).scrollTop($(document).scrollTop());
$(w.document).scrollLeft($(document).scrollLeft());
}
else if(mode == 'dp')
{
$(opener.document).scrollTop($(document).scrollTop());
$(opener.document).scrollLeft($(document).scrollLeft());
}

[/CODE]

This is supposed to scroll both windows or tabs, and it does it great on Opera.

But Firefox, [s]Google Chrome[/s] (Just tested it once more, and Chrome does it flawlessly) and[s] Internet Explorer[/s] can't withstand it, and [s]they three[/s] [s]both[/s] it lags.

The lag is clearly visible when using the up/page up and down/page down arrow keys.

Any suggestions?

Ok. Seems the one having problems right now is Firefox. Strange, I've tested them a couple of weeks ago and they did have issues. :/

Anyhow, I don't complain.

If you know a better alternative, let me know!
