I'm running into new problems when I export PDFs from Photoshop. In all my years I have been able to Save the original PSD. Then do a Save As PDF, then close without saving changes. All of the sudden in the last 3 days, EVERY time I export it saves over my original PSD with a flattened PSD. I'm carefully reading the dialogs when I'm doing this, but I can't seem to figure out why this is happening. I've had to remake my last few projects and I'm losing a lot of time because of this. Anyone have any ideas besides saving multiple backup files on separate drives? Did something change about photoshop exporting in the last few days. Thanks!
