No, you have no control over the minimize button of a new window (unless
you're talking about Microsoft specific modal dialogs)
Use showModalDialog which is only applicable to IE
If you call the function given below from your code, it will open a modal window, which will not have the minimize/maximize buttons, but it does not take care of the close button.
function showWin() { var newlookup = window.showModalDialog("http://www.yahoo.com", "", "","status=0;help=0;dialogHeight=" + 400 + ";dialogWidth=" +600 ) }
