Internet Explorer 5.5 SP1 includes support for Dynamic HTML, Java, and the Channel Definition Format (CDF). An AutoSearch feature lets you choose your search engine and display search results in different ways. For example, you can choose to be redirected automatically to the best-matched site. In the History box, you can sort the list of sites by date, site, most visited, or the order visited. The AutoComplete feature displays a drop-down list of matching sites when you start to type a URL in the address bar. AutoComplete also works with Web forms, displaying a list of previous entries when you start to type in a field on a Web site. To automate login processes even further, you can also save usernames and passwords for particular sites. Internet Explorer offers 128-bit encryption and includes a Radio Toolbar, which allows you to listen to radio stations over the Internet as you browse. IE also allows you to select the default email, calendar, newsgroup, and HTML editors of your choice. You can even designate your Web-based email provider as the default email program. Version 5.5 SP1, the latest in this Web browser line, includes improved support for DHTML behaviors, as well as additional support for vertical text and existing standards such as Cascading Style Sheets (CSS 1). IE 5.5 SP1 also features additional support for the Synchronized Multimedia Integration Language (SMIL). A print preview feature has been added, as well as improvements in printing performance and several Internet enhancements that will be included in the upcoming Windows Millennium Edition. This build introduces new language features in JScript and VBScript, and a frames re-architecture. IE 5.5 SP1 features Active Setup (a 499K file), which requires that you maintain your Internet connection after you double-click ie5setup.exe. Active Setup will prompt you to choose among various IE packages; these range in size from 8.5MB to over 40MB, with a typical install of 15.4MB. You can also opt to download the full setup package: run the ie5setup.exe setup file, select a minimal/customized installation, click the Advanced button, select the Download Only option. This is practical if you need to setup IE 5.5 SP1 on more than one machine. Note: For a non-English version of IE 5.5 SP1, go to the homepage, then select your preferred language.
