I recently "upgraded" to Lightroom/Photoshop CC. Within the last week when trying to select multiple images in Lightroom, I have not been able to. Lightroom only lets me select one image at a time. I cannot find any threads dealing with this in the forums. Have I inadvertently turned these features off and if so, how do I re-enable them? Restarting Lightroom does not fix the problem. Thanks in advance.
Ok, this seems weird, but on a whim I decided to hit T to toggle the toolbar below the grid even though it was visible. After doing that, I am able to use Shift Click and Command Click. I don't know why, but it seemed to fix the problem.
