I'm new to the software, using blender 2.78 on an iMac with OS X 10.6.8. I've been working on a file for a few days now, when a important panel to the right suddenly disappeared.
This is how it looks right now:
The panel marked in red in this picture is the one i need:
Notice how the three lines in the corners that you can grab to change the size of view windows/panels also is gone in the file I'm working on. Marked with green circle in top right corner.
Edit: Solved the problem by opening the file with "load UI" unchecked. Still wonder why the three lines in the corners of the panels disappeared though.
