2.8 Can't connect compositor nodes

Hey there,

having moved to Blender 2.8 I’ve gone to use the Compositor for the first time and then realised I can’t drag node connections from one node to another node. Like here…

But I can drag connections to nodes in the Shader Editor.

Am I missing something?

Thanks in advance.

Did you do a render before moving to compositor?

download a newer beta vision from blender.org. The problem maybe solved by developers.

Actually in the end it seemed to be because I had 2 Compositor viewport windows opened at the same time.

Weird, thanks anyhow.
