Cannot drag and drop photos from filmstrip to a collection- is there another way to add them?
I am using LR CC 2015 on an old Mac running OS Yosemite that cannot be updated (updating from Mountain Lion to Yosemite pretty much destroyed the performance of this machine, which is now painfully slow, even with more RAM added). I cannot drag and drop photos from the filmstrip to a collection as shown in current tutorials. Is there another way to add a photo to a collection? I have searched the menus to no avail. There is one menu item called "add photo to target collection." But I cannot figure out how to set a collection as a "target collection" or even find an explanation of what that is.
