Part of Blender UI Windows disappears l have been creating a scene for sometime now. All of a sudden, the part of blender that has the File, Render, Window ,Help  you know, the part of the blender interface that allows you to switch between blender render and cycles and stuff..
It just vanished and was replaced by a programming window. Now, all I see are codes instead....
Any help?
On the far right of the part of the screen you circled you will see a little plus sign. Click that and you will restore your view.

Somehow you pulled down the menu to hide it. The plus sign in the interface lets you know you have some of the interface in that view hidden.
