Okay Johnny, then I have to ask if the image was moved to a different layer after it was imported? In my testing using TC V10, I found that I could not move any added trace lines under the image, not even the arrange tool would do it. Once moved to another layer then the layer would be on top and added lines would go under the image. I also saved the file and reloaded it to see if that caused a problem but no change. I feel confident that you changed the image layer after it was imported. Let me know if your experience with this is different.
