Search scopes

Tech-Archive recommends: Fix windows errors by optimizing your registry

I am setting up a new Sharepoint site and need to move an existing site
onto it. I have created some search schedules but need to edit and
delet some of them. I am on my 'Manage search schedules' page but there
is no drop down list appearing ? I can't work out why.

It is a new site and the actual content documents have not been moved
into place, this could not be affecting this though could it ?

Any help would be greatly appreciated.
