All of the suggestions should have worked so "in desparation" I did a complete rebuild of the whole project (instead of the incremental build that was happening automatically). The problem disappeared! Both redraw() and redraw_label() work but I suppose that redraw_label() is "more precise" here. Thank you again. Al koch Thank you.
