Another intreresting behaviour in IE5 is the download behavior: http://webfx.eae.net/dhtml/download/ <SNIP> What is it? The download behavior is a ie5 behavior that allows you to download any file without having to reload the page. This is very useful, for example it can be used with tree views so that the sub items are not downloaded until you expand the parent. It can be used for a lot of things, including submitting forms (GET method only), use your imagination. </SNAP> This behavior come well in hand when implementing a link tool for ZIE or a Image browser, and make it possible to save in the background perhaps? Here a reference to all default behaviors in IE5: http://msdn.microsoft.com/workshop/author/behaviors/reference/reference.asp you can find this and other useful links about IE5 at the ZIE-project: http://www.zope.org/Members/johanc/ZIE/rel-links //johan
