Search text box is not working properly in IE 8, text box is not visible.
Isn't it more likely that it's IE7 that's having the problem? :-) Seems like the "compatibility view" has been enabled on your screenshot?
When I watch using IE8 standards mode the search box is showing up just fine. When watching in compatibility mode the error occurs.
You are right this is actually IE7 issue, and my browser was in compatibility mode. It works fine in IE8.
Thanks for your reply,
