The problem which caused these undesired messages was one of sequencing.  I had opened a DCWindow, resized the FXRGBImage, then done all my changes.  Doing the resizing first cleared up the messages.  In hindsight the messages look appropriate.

Thanks for the tip on FXTRACE, it's a great feature and was quite helpful.  I think I'll make a habit of using it.
