Comment 1 Christoph Roick 2018-06-01 22:12:14 UTC

Do you remember if you had any toolviews opened? I was struggling with something similar recently.
Where exactly did you click?

Comment 2 Nicolas 2018-06-02 14:23:52 UTC

I had the default view open, and I clicked into the editor (source code) window after it was inactive

Comment 3 Justin Zobel 2020-12-17 05:39:10 UTC
