Yes, that's normal: because you can't insert text onto an image.  What you did was put floating text on a print (or a page) and those have to be printed.  The only thing in Qimage that puts text onto an image is the info stamp in the image editor.  This falls into the category of "images versus prints".  They are really two different things in Qimage and you can do different things depending on whether you choose an image operation or a print operation.

Appreciate the explanation, Mike.  I had the exact same experience as Jeff and solved it the same way.
