xp64 search box

[hughwilliams]

running a quad core amd processor, 4 gig of memory windows xp64

i have had to have a new mother board fitted to my home computer and since then i have installed all updates etc and when i attempt to run hoster it comes up in the bottem bar, i then restore it and it opens up ,, when i then hit the search box it appears in the bottem bar but will not pen. I have upgraded to 4.09d, i have used the uninstall and reinstall but no change, any ideas would be appreciated.
