I downloaded the latest version and found a small bug.
I found out that when I save to PNG via the FILE->Save Image it does prompt for new file selection, but it doesn’t save the file path to the project.
Only save-as on the same file adds the png file name to the project.
could not duplicate this problem but what I observed was the following:
create a project
save as project file
use “save image” to save an image file.
–> Now the project is not marked as “has changes”. That means you can close the project without a warning. If you do then the image file name is missing in the project file next time you load.
I guess this is what happened?
