Windchill 10.0 search issue_I can't search!

Hi,

I don't have this issue yesterday.

I entered p/n into search area which nearby 'Quick Links' then execute search, But in Navigator I got error. There is no 'Search Results' box shown. Seemed like I never perform the search action.

Even if I open 'Advanced Search', the 'Type','Content','criteria' are not response when I click them. And my 'Search' button at buttom is disappear.

I tried clear all my IE8 browsing history and also reset my IE8. It's not working.

But it'll be OK if I use Firefox.

Anybody who know what's going on here?

Thanks in advance,

Sylar
