For some unknown reason, when I try to connect 2 nodes, from the cycles node group editor, I cannot draw a line, but instead it draws a select box what can I do against it?
I'm unable to progress my work now as I cannot finish the shader work, I cannot make a screenshot about it, its just as when one would make a group and had typed B (only I don't start with that crosshair cursor)
