Hi George.
I think I found the culprit. As you can see on the attached image, the solution is to have "Converting local files paths to relative" unchecked.
Now, the thing is that we've been working with this option checked from the very beginning of Corona and it was never an issue. So as I mentioned in some of my first posts, there must be something different in the way this new version of Corona handles paths, so that this option can't be used anymore.
Maybe now you have a better idea of what might be going on. I'd really like to understand this issue.
