Snapping not working for curves with picture frame in background

Also can not send picture frame to back. Had to bring curves forward.

Hi Bill - if the curves are behind the picture, then the snapping behavior will follow the ‘Snap to occluded objects’ setting in Options > MOdeling aids.

Does that do it?
