As you add or remove search fields (using the green [+] and red [X] toolbar buttons respectively), or when you resize the main window, toolbars can get out of shape. You have many ways to bring back order:
Another issue I hear about is the preview window. By default this is autohiding, but if you click on the little pin button on the quickviewer's titlebar, you will make it stay extended. You can then drag-drop the pane and dock it somewhere else (e.g. left or bottom side). You can also resize it, even have it floating outside the deskrule window (double click on the titlebar for this feat).
