Pop,

Can you set the graphic and text up in an mxd with a scale dependant layer (do not show when zoomed out past) so when you zoom out it turns the graphics off

or

if the graphics are drawn in the viewer itself then on the zoom functions set the code to something
like:

on zoom out

if(map.scale > 5000)
graphicsLayer.visible = false;

on zoom in

if(map.scale < 5000)
graphicsLayer.visible = true;

Regards

Anthony
