The Planner popup window (from CONFIG screen) does not close if Planner page is clicked on CONFIG screen.

1. Start Mission Planner and then click on the CONFIG tool strip menu button.
2. Double click on Planner page to pop it out to a separate window.
3. Go back to main window on CONFIG screen and click on Full Parameter List.
4. Then, on the same screen click on Planner. The Planner page appears correctly on the CONFIG screen but the popup Planner window is still there. It should be closed.

Reproduce the CONFIG screen sequence: pop out Planner, open Full Parameter List, then click Planner again. Trace the Planner page and popup-window lifecycle in the Mission Planner desktop application; done means selecting Planner on CONFIG closes the separate popup while showing the page in the main window.
