I've been trying several different ways of setting Photoshop CC as the default image editor in Windows 7 and this appears to be blocked. The system ignores my selection of PSCC and randomly applies PDF or Dreamweaver or itunes or Windows Photo Viewer to opening of Jpgs and JPEGs. This is so bizarre! Is anyone else having this problem. Windows was even converting downloaded JPGs into PDFs or even itunes rather than permit PSCC to be assigned to the file type. What am I missing??
