The subject behavior prevents you from seeing all of the windows content, because this window does NOT contain scroll bars.
This behavior will occur of the Web site used the window.open method in the HTML of the Web page with the resizable=no feature. Previous versions of Internet Explorer ignored the resizable=no feature, but Internet Explorer 5.5 and later honor the specification.
Try the following workaround:
1. Right-click in the new window, and press Create Shortcut and press OK.
2. Close the new window.
3. Double-click the shortcut that you created in step 1. This may open in a typical browser window that you can scroll, maximize, and resize.
If this workaround does not resolve the problem, contact the sites Webmaster.
