I am, as others, delighted with v4.30, particularly with the Light table feature that allows me to visually sort the pictures into any order with "drag and drop" I was mystified when I tried to sort my initial folder of pictures (file panel - keyboard F3). The highlighted picture could be dragged (and looked semi transparent) but could not be dropped into a new position. After some experiments, I discovered that only pictures in the slide list (slide list - keyboard F4) can be dragged AND dropped with a light blue square showing where the drop occurs. To initially sort all of my folder pictures into some sort of order (drag and drop) and delete unwanted ones, I added (Cntrl + A) all the file panel pictures to slide list, then (with F4) sorted and deleted pictures till I got a manageable slide list. Am I missing a way of sorting my file list with drag and drop? With the Light table and Waveform showing, PTE just gets better and better. Boogie
