Editor-menue non-functional on non-new project

This sounds like it might be the same as this? https://answers.unrealengine.com/questions/67322/undefined.html

Compiled source, version 4.3.1

Clicking on any item on the menubar or toolbar has no effect besides tabbar alternatively changing to a lighter/darker color.

Sourcecontrol-inputfield however can be used.

This does not apply to a new created project.
