panel missing until I change view how do I get it to stay?

Hi

I am currentley trying to download plenty of good addons and for the few that I like and have been added successfully there doesn't seem to be a panel, until I go to view and click main panel.

However when changing the shot to see myself from the tower etc and then returning to the cockpit the panel is gone again?

So basically the cockpit won't stay up or (panel) won't stay up?

Does anyone know how to change this?

Thanks.
