For some reason a couple of my toolbars that used to be in my main tab have come free and I can't re-dock them. For example, my Wedlments toolbar I can click and drag around, but I don't want that. I want it back in the big tab/toolbar/whatever it is called along with Sketch, Features etc. I have tried double clicking on it but doing so just places the floating toolbar next to the main tab. Right clicking on it just produces a list of other toolbars. I don't know why this is so hard for me, can someone please let me know how to do this.
