So i was working, as always, everything is fine, when i clicked the right click to bring up the quad menu it just won't come up all of a sudden, it just happens in viewports, if i clicked on the toolbars or anywhere else it’ll work, once i want to isolate the object the right click menu won’t show up. went over the net they talked about transpirty in windows still didn't work.
Your help is appreciated.
