Only can think I copied a corrupt / graphic?
That's certainly possible, I've had a corrupt graphic crash FileMaker in the very distant past.
Is the graphic in a container field? Are there any PDF's in container fields on the layout in question?
Thank you for your post.
Since the original file works, you may have a bad layout or bad file. To see if it is the layout, create a new layout (do not duplicate), and create the same fields and objects on the new layout (do not copy and paste). If you cannot duplicate the issue using the new layout, then your original layout is damaged. If this is the case, delete the original layout and continue using the new layout.
If the problem still exists in the new layout, then your file may be damaged. Export the new data from the damaged file, and import it into the original file.
Let me know if you are able to further narrow down the possible causes.
