Strange behavior - unable to drag and drop photos to folders in Library mode?

Thanks for the replies!

Ok, that takes care of the select part, now we just need to see why I am not able to rearrange my footage across folders anymore.

In all of former Lightroom instances and all the catalogues, I could cust drag and drop the photos onto the folder icons in the file structure in the left pane, and the photos would be moved into that folder.

Any ideas?

Now, when I click, the photo gets selected (borders a bit highlighted), when I click on the next one, it gets selected and the first one deselected.

That is normal behavior. You have to hold the Shift key if you want to select multiple adjacent images, or the Cmd key (not the Ctrl key, that's on a PC) if you want to select multiple images which are not next to each other.

You need to select one photo by clicking on it, then control-click on the next photo, and so on.

Also, another approach if there are consecutive photos you want to select, is to click on the first photo and then shift-click on the last photo of the consecutive group of photos.
