When the search Results window opens in a docked state, the main window is not resized. This can result in double clicking on a line in the search results window, but then not being able to see the highlighted line because it is behind the search results window.
When this happens (it seems to happen every time for me), the push pin icon displays vertically. Hovering over it will display the "Auto Hide" tool tip. Clicking the drop down arrow to its left will display the context menu with Docking selected. I have to click the push pin icon (which causes the window to minimize/auto hide), then click the Search Results tab at the bottom of the main window, and click the push pin icon again to get it to properly dock and resize the document window.
