Scrolldown with FireFox

[Rodie]

Hi all

I have a web page with an <iframe> called: myiframe
This frame contains a <div> called: mydiv

In a javascript function, I try to scrolldown the <div> like this:

oDiv = window.frames["myiframe"].document.getElementById("mydiv");
oDiv.scrollTop = oDiv.scrollHeight - oDiv.clientHeight;

This piece of code works fine with Internet Explorer. But with FireFox, the 2nd lines generates "sometimes" an error (everything is blocked, pending).

Someone has an idea ??
Thanks for your help

Problem solved:
actually, I should have encapsulate the second line in a try-catch because when the scrolldown is not necessary, it generates a blocking error.
