No, it displays the list in the upper frame of the tab where I logged in. I suggest that you take "in this frame" to mean literally the current frame or window where the search form is opened, not where it thinks it was opened. With the tabbed interface and the habit of UT to lose unread messages on every refresh, we tend to do other tasks in separate windows/tabs, just to preserve the state of the main window. Often I start to reply to someone and then need to do some searching, and for that I open the search form in a new tab. Then the search results appear in the frame where I was writing - or, if I chose the "above frame", in the message treeview, which then makes me lose the list of unread messages.
