Trouble w/ Smugmug publish service in LR3.6

Delbean

I am losing my mind! I used to be able to highlight a bunch of photos and drag them into new galleries I've created under the SM Publish Service, but for some reason I can't drag photos over to the gallery in the left panel anymore - not single photos, not multiple photos. Nothing. I can highlight them singly and as a group, but when I go to drag them they become un-highlighted. This worked fine until a week ago. I also have a Facebook publish service that I can't drag pics into. Please help me!!!!
