Invaild editor window error on "Maximize on Play"

Unity Engine
1

I keep getting the follow error when I use “Maximize on Play”:

Invalid editor window UnityEditor.AddComponentWindow
UnityEditor.EditorApplicationLayout:FinalizePlaymodeLayout()

It doesn’t seem to have any ill-effects but I’m getting tired of seeing it. It even happens on a complete empty project (I just checked). All the research I did (and by that I mean I Googled the error) seems to indicate an errant script but since it happens with absolutely no scripts in there, I don’t think that is my problem. Any thoughts?

Thanks!

Got this error with version 5.3.6f1 today.

Resolved by picking Window > Layout > 2 by 3 (this resets the layout - and then running with Maximise on Play on).
Following that I then rearranging the layout back to how I like it and tried running again with Maximise on Play on - no error appeared.
