difficulty dragging and dropping with new trackpad
feeling a little inadequate trying to simply drag&drop with the trackpad on my new MacBook Pro (13-inch, 2018, Four Thunderbolt 3 Ports). More often than not when I go to drag & drop all that happens is I end up opening the file or image... any secret to successfully and easily doing this basic function on this new trackpad? Could I be the only one with this problem? Thanks in advance.
MacBook Pro (Retina, Mid 2012), iOS 10.3.1, info says: High Sierra 10.13.1
