When you have silkscreen on both sides, then select something on one side, go to the other side and shift-click there, the things from the other side will not be added to the selection. Instead, things from the first side which were already selected and are on the same coordinates will be subtracted from the selection.
And this happens even if all layers except silk are turned off. Far side is also turned off. I think it should manipulate the object you click on and nott anything on the other side. CL<
