You missed to tell what happens. From what you wrote you want to say the text does not come to front when you have edited the JPG? That can't be.
But why use "Bring to front" anyway, instead of placing the text in a different (higher) layer?
I seem to have been doing it that way for awhile, with no worries. So now I tried to create a new layer. placing it above the other layer and I seem to be having the same issue.
The issue plainly is, I used to fill in a color in my text frame, but this time I wanted to try a texture file from Digital Juice and when it appears "darker" my text won't go on top of it. Yet when it is washed out - which I don't necessarily want, the Text stays on top.
I hope I still haven't confused you.
I see. So there is no extra image object, but a background fill. Please make an example of BEFORE and AFTER and post a screenshot here.
