[Users] Geoext Popup Question

[Jason Woolard]

Cool.. Thanks Adam!

That answered both questions and fixed the popup behavior. It was as 
easy as:

var selectCtrl = new 
OpenLayers.Control.SelectFeature([kmllayer1,kmllayer2,kmllayer3],{
                toggle: true,
                clickout: true
        });

Thanks again for the help..
