Text scroller Firefox

[flux]

Hi everyone,
I have a problem with the text scroller in Firefox.
I've noticed when i adapt the
#divScrollTextCont{clip:rect(...)} and the
#divText {position:absolute;left:0px;top:0px;width: 335px;height: 340px;}
the scroller works fine, only problem is that i use an external css file for multiple pages, and obviously i dont want pages to scroll when there is no text to show.
So basically the problem is: the divText{} has a certain size, when my text exceeds this size, the scroller works in IE but not in Firefox.

maybe its a bit clearer when you see for yourself. At this moment i havent changed settings for divText and clip:rect().

Tkx for the overwhelming response on this topic []
But i'll solve it this way:
i'll overload the height property in css of the divText.

<div id="divText" style="height:...px;">
</div>

it seems to work this way.
Anyways tkx for reading this.
