Designer perspective tabs

Migrateduser

<p>Quick question about the tabs in the layout editor. Somehow, the tabs are not in the same order as when I first installed. They're now (DesktopViewer (prototype), Layout, Master Page, Script, XML Source. Is there a way to change the order so I can have Layout as the first tab ? I tried looking at all of the preferences, dragging the tabs, and even reinstalling, but I can get them to go back. Attached is a picture of how they currently are.</p>
