Either I've done something or something has changed.
In the past when I scanned my local network all the computers (5) would have a plus sign (+) next to them in the display screen, on the left. When I clicked on the plus I could see the other computers disk drives, etc.
After an update (maybe?) I can no longer do this and all the other computers on the network no longer have a plus next to them.
Perhaps ticked the wrong box and can't find it again or??? Please advise.
