Since last update, it's not possible to move (Move tool) a multiple selection or a layer group. In that case photoshop move and select the layer with content under the mouse pointer only. But CTRL + ARROW KEY or "Free Transform" (CTRL+ T) allows me to move multiple layers selection.
»So please bring back this usefull feature.« So how about you first check your settings? What are the Move Tool’s settings in the Options Bar, like »Auto-Select«? Could you please post screenshots with the pertinent Panels (Toolbar, Layers, Options Bar, …) visible?
If a Tool misbehaves the Options Bar is usually a good place to start looking for unwanted settings; if that does not prove useful resetting the Tool or even resetting Photoshop’s Preferences provide further trouble-shooting options.
