Assuming you were trying to do something like, Response.Write("<script language='javascript'>window.close();</script>"); don't use ~~window.close();~~ and instead use parent.document.getElementsByTagName('dialog')[0].close(); as stated at the bottom of the README

parent.document.getElementsByTagName('dialog')[0].close(); does not work for me.... I get: Cannot read properties of undefined (reading 'close')
