Hello, I just gived Mozilla M18 a try and noticed that <Back> Button of the browser doesn't work in zopüe management screen. Netscape 4.75 (and for sure other browsers) works well. Is this more a Mozilla or more a Zope problem. I expect the first but may be someone could write a more qualified bug report than me because I'm a bloody zope beginner and may be knowledge of some details might help the Mozilla developer. Kind regards Andreas.
