window doesn't center

[scorp]

I am trying to load content in a window using the ajax call. However the window is not centered on open.

var win = $("#CreateUserWizard").tWindow({title:"My Window"}).data("tWindow");

    win.ajaxRequest('....url to form.....'); 

    win.center().open();

I would have to "resize" the window when the content changed

$(win.element).find(".t-content").width('auto').height('auto');
