While editing new images from last weekend, the computer starts “ponging” or “stuttering” super fast and then drops the entire adjustment pane, leaving only the image. Also, the tool icons at the bottom of the computer disappears. All that is left is the image from the project. Is this a dysfunction of the application? If so, how do I proceed to correct it? I have a deadline looming very soon. As always, hoping the experts will be able to recognize this error and help me out; thanks.
