I am using window_widgets with either a map() graphic or image () graphics. I still need the user to be able to click on the map so I can get points from the user clicks, but I don't want the user to be able to zoom, rotate or translate the graphic.

Hi Chris,
I have been working creating a class for handling events. Things are moving along slowly but I think I can do all the stuff I need with this. But I have one question - I am trying to override the selectChange method. How do I change the selection of the graphic directly? I can't do graphic.select (or graphic.select, /clear) since this calls the method I am trying to override and I end up with an infinite loop. Does this make any sense?
Thanks,
Paul
