Cannot Move Photos to a Different Folder From Within Lightroom

Hi There -  Since  I  can't replicate this in my  Lr catalog can you tell us if you've also tried to drag and drop a  group of selected images from the filmstrip  at the bottom into a new folder?

Another way to move images within Lightroom is to select all the images that you want to move, then right-click on the folder that you want to move the images TO. One of the options will be to move the images to THAT folder. That option seems to work well for me.

Are you pointing your mouse at the actual thumbnail image when you hold the mouse button down? (It won't work if you point the mouse at the grey area around the thumbnails and hold the mouse button down)

Workflow suggestion: instead of moving photos from here to there, assign stars or color labels to the photos you want to consider as "maybe". For example, after you have selected the photos, press 7 to assign the Yellow color label; this is much easier than creating a new folder and then physically moving the photos via drag and drop.
