Right click within the window. You’ll get something like this:

I definitely recommend trying more current versions of blender if you can.
You can get the current build on
If you cannot use 2.8+, then try out the 2.7+ series.
For 2.79b and previous builds, go here

Your current build is from year 2013

When you open a blend file, uncheck the Load UI
