Omni Slide in ASP.Net : Disappear after Postback

[msasono]

1) Script Title: Omni Slide

2) Script URL (on DD): http://www.dynamicdrive.com/dynamici...lide/index.htm

3) Describe problem:
I am using this script with ASP.NET 2.0 . It is working properly every time the page load at the first time. However when we do a Postback (such as changing a drop down text to fill the value to a text box), the menu will disappear from the screen. Please help, Thank you.

Problem solved. I was using the obsolete smartNavigation property. turn it off, and the script working properly without disappering after postback.
