Closing & reopening the Outliner causes the window to move.

[Pjanssen]

What steps will reproduce the problem?

1. Open the Outliner.
2. Close it.
3. Open it again.

What is the expected output? What do you see instead?
Window should be opened in the same position. Instead, it seems to shift 5pixels down, and 5 pixels to the right.

Please use labels and text to provide additional information.
Possibly only in win7?
The shift itself seems to occur after cui.unregisterDialogBar when closing? Perhaps storing the position after this command causes the issue?
