In Altium I don’t have any connections (ratnest) showing. They were showing previously, and in the viewer they are ok. They should be visible after going to view->connections->show all but are not. This happens on all the boards and workspaces I open.
There are plenty of unconnected SMD that highlight when I mouse over. The DRC report gives lots of unconnected pins. The net color doesn't match the background, and a few nets have special color assigned. All of this seems like the connections should show, but no luck.
