I'm running 10.5.5 on a G5 iMac. When I use Spotlight from the menu bar to search, it displays the expected results. But then when I select "Show All," it opens a blank Finder window. My search term is there, but nothing displays in the results window until I modify the search term (for example, remove the last character, then put the last character back). Shouldn't I see my results? Any idea why it's behaving this way?
