fading scroller

**gauri_agr** · 11-24-2009, 03:47 AM

Hi All,

I am using the fading scroller. The link is as below
http://www.dynamicdrive.com/dynamici...fadescroll.htm
I want to pause when mouse is on the message. But I very new to javascript and unable to decide where should I change the code and what.

Thanks & Regards
Gauri
