you're right ! many thanks. I don't understand why some OMGraphics
built in the layer can be displayed before ... that's another story ...

I have another problem.

I have to find all OMGraphic which intersect an area (rectangle or circle).

There are many functions to find closest OMGraphic but I don't find a
function which can give me a list of all OMgraphics closest to a point
(with a distance papameter for example) ...

I forget another thing or I have to write it ?

many thanks.
