If you open up Pixlr Editor or Pixlr Express and see a grey or blank screen, you’ll want to reinstall Flash.
Pixlr Editor and Pixlr Express are Flash-based apps, and from time to time Adobe updates Flash.
If your computer is running an older version of Flash and you see only a grey screen, a quick update or reinstallation of Flash should get you back up and running.
Visit this page on Adobe’s site, which will show you which version of Flash you’re running. You may be prompted to update Flash on your computer.
Note: You will need to restart your browser before launching Pixlr Editor or Pixlr Express.
Note for Chromebook users: You may not be able to reinstall Flash manually. Flash may be tied to an automatic Chrome update for Chromebook users.
