File with named shapes to test Navigator

Error: Changing nav-order in Navigator does not work, if only one page exists.

To reproduce the error:

Open attached document.
Open the navigator as floating window by pressing Ctrl+Shift+F5.
Go back to main window, but keep Navigator open.
Press Tab-key several times.
Notice, that the order of the shapes in the Navigator is the same as the order in which the tab key goes through the shapes.

Now try to drag the "Rectangle" shape before the "Triangle" shape or to any other position in the Navigator. You will always see a 'forbidden' sign.

Insert a second page.

Now try again to drag the "Rectangle" shape before the "Triangle" shape. Now it works.

Go back to main window, but keep Navigator open.

Press Tab-key several times. Notice, that the order in which the tab key goes through the shapes corresponds to the changed order in the navigator. So changing nav-order via Navigator works in principle, but not if only one page exists.
