We can't know. You have not provided any pertinent system information or other technical details.
What specific information would you need? The program was working just fine early yesterday morning and than when I came back in the afternoon to edit some more pictures that is when I wasn't able to see the full image anymore. It is providing me with all of the editing options as if the picture is there but it is just a blank screen with the thumbnail pic showing in the right panel.
Oops. My previous reply was meant for another question. Can you tell me what pertinent info you would need? Thanks.
