I am running my new LR on my new MacBook, and my touchpad drag-and-drop works everywhere else (including Photoshop), but not in LR. i.e., I can't rearrange the order of photos in a collection or drag-and-drop one into an existing collection. What do I need to change?
Maybe saying what you already know-
But are you dragging by placing the mouse cursor on the "Image" area of the grid thumbnail?
You cannot drag if you click and drag the cursor from the grey border of a thumbnail.
If it is a smart collection, drag and drop doesn't work
Yes! I can't believe that I was that clumsy or ignorant. None of the tutorials or the Kelby book mention having to put the cursor in the "image" area.
