Lost window control

[AncientPuffer]

Twice now, I have slid the "favorites" window all the way to the top of the screen, in order to click a location on the map, to record a new favorite.

When this happens, I can no longer click on the top bar of the favorites window to reposition it. The last time this happened, I was unable to find an answer in the forums, so I had to do a complete re-install.

Is there another way I can get my favorites window back to it's normal location?
