I do not have a "Enable/Disable Ground Traffic" option on the YouControl menu.
Yes, you surely have it, because KMEM menu has such option.
And I'm not talking abt GSX traffic but the scenery traffic itself.
That's exactly the traffic I was referring to, that's why I said "YouControl menu" NOT "GSX Menu". YouControl menu it's a menu related to the AIRPORT ( not GSX ), which uses the same key that can also use to call GSX, on airport that doesn't have its own YouControl menu.
On a scenery that DOES have a YouControl menu, like KMEM, pressing the YouControl key ( NOT the direct to GSX key, which by default it's CTRL+Shift+F12 ), will give you a choice between choosing the AIRPORT own menu ( YouControl ), or proceed with GSX.
And on the airport own YouControl menu, which here is labeled "Memphis International Airport", when you enter it, there are several options, including the one to Enable/Disable Ground traffic.
