I used to have Photoshop Elements 10. When my hard drive crashed recently I updated to PE 19. I used to be able to upload multiple photos/images into the program and could cascade the images so I could see more than one at a time. I have tried to do this in the new program and have used the command but it will not allow me to look at more than one thing at a time. Makes it impossible to work in multiple layers. What am I doing wrong? Thank you for your help.
As Greg_S rightly mentioned, there's an option in the Preferences to allow floating documents. To make this change, please press Ctrl + K (Windows) or Command + K (Mac) and check the 'Allow Floating Documents in Expert Mode' checkbox.
Thereafter, you can choose your preferred floating mode setting under Window Menu > Images.
Hope this helps! For any further queries, please feel free to respond on this thread.
