wair, you're all scarrying me:
i often do things like this:
var datascape = new Object();
datascape.el = $('#datascape');
datascape.ini = function(){
datascape.el.click(function(){
dothis();
dothat();
});
}
is this pattern causing a potential memory leak problem, because the
js object is linked to a DOM element?
