Firefox 2 ASP.Net No Focus on Textboxes

[johnbear]

This one is driving me mad. On my site http://www.cherrything.co.uk you will notice a search box. This works fine in IE.

However, it doesn't work in Firefox 2. You cannot get the text field to obtain focus.

But if you right click over the field you can set focus on the textbox.

I've checked Google but can only find references to articles regarding the cursor not showing i.e https://bugzilla.mozilla.org/show_bug.cgi?id=16780...

I've tried the fixes such are overide on the div, to no avail.

Any Ideas?
