The problem was that, under particular conditions (many redraw of images), my 
blinking could become irregular,
as timers, if I understand well, are all at the same "priority level".

The technique you and Greg told me is clear ; will "clean up" something in my 
(growing!) app and try
to avoid unnecessary redraws.

thank you a lot for your precious help.

Best regards,
