I had the W working in my last 2.80 version which was perhaps 2 weeks ago. As of today, 06-05-2019, W or specials menu doesnt show and returns an error. Also search for “context menu” doesnt give any results. Right clicking in the viewport with a selection active also does nothing?!
Also why does W in object do show a context menu than?! I dont understand some of the choices they are making, they are shuffling so many things around.
they changed the operators name. OS right click in the viewport will never work since that is deselect.
