When moving an object, it drags and tracks duplicates continuously

any idea what has happened to my settings… ??.. its very simple, if I try to drag an object from one place to another in my drawing, it “drags it across and tracks with lines”… so its like the object is making a copy of it self all the way… if that makes any sense ?

Please run SystemInfo in Rhino and copy paste the results here.

not sure how or what, but “pushed some things” and now its working as it should again… so sorry and many tx for having a look…
