If I enter into the Javascript console: tinyMCEPopup.close ();
It returns: TypeError: Unable to read the 'windowManager' property from undefined
Thank!
Inside the popup, I call the following:
parent.tinyMCE.activeEditor.windowManager.close(window);
Try:
win.ed.windowManager.close(this); //where //win is parent window //ed is tinyMCE object
Hope this helps
