The "Search Posts" feature found in Manage->Posts never returns any results, even for posts with titles including the search term I know exist. It always says "No posts found".
The settings in that page are the defaults: "All Posts", "Show all dates", and "View all categories".
p.s. The template for entering posts to this support forum should be updated to include version 2.5.1 of WordPress (right now it is just 2.3.3 and 2.0.11 !).
