Re: Extra Click Event

Hi Peter,
You could try these things:

1. Check if you are getting the exact button element just before you associate the connect event.
2. Check if the dojo.connect returns the right value(some array descrining your onchange event and its associated elements)
3. Try doing awindow.onload, bcz I have faced some similar problems with the dojo.onload() but it was long back.

Thanks and Regards,
Vikas A Patil

I have the following code and the problem I am having is after I select an
item from the combo box which causes an OnChange event like it should but
then if I click anywhere on the screen I get a second OnChange event from
the combo box, how do I prevent this extra OnChange event

Thank You

Peter
