Sorry if this is a bit trivial or a ridiculously simple fix but I’ve tried a number of things none of which have worked. For some reason I have suddenly got a grey line that goes back to the origin point any time I try and move something. I have tried ‘switching off all guide lines’ in the control box but its still there. Its not stopping me from working, just a bit annoying. How did I get it in the first place, and how do I switch it off?
