I have released a new version of my Prototype Window Class (http:// blogus.xilinus.com/pages/javawin) - Add autoposition in setContent. The window will be at the exact element location - Add draggable/closable parameter if you need to specify is the window is draggable/closable or not - Add parent parameter if you need a specific parent element of the window instead of body (useful for forms) - Better resize - Add setCookie to store window location/size in a cookie And I have also created a mailing list to have an easier way to send bugs/feature requests or any questions. Thanks a lot to all of you guys that helped me in this project Seb
