IE7 incorrectly recognizes an intranet Web site as an Internet Web site
When you visit an intranet Web site, Windows Internet Explorer 7 incorrectly recognizes the Web site as an Internet Web site. Therefore, if the Web site requires user authentication, you are prompted to enter the user account in the domain and to enter the corresponding password. You expect Internet Explorer to automatically send user authentication information to the domain when you visit an intranet Web site.
This problem occurs if you configure Internet Explorer 7 to use an automatic configuration script.
Notes
• In Windows Vista, this problem does not occur when the User Account Control (UAC) feature is enabled.
• This problem does not occur if you visit an intranet Web site by clicking a link in a Web page.

Windows behaviour is incorrect when you use a program that uses DDE to browse pages in IE7
Consider the following scenario:
• You start a program that uses Dynamic Data Exchange (DDE) to browse Web pages in Windows Internet Explorer 7.
• In Internet Explorer 7, you then click New Window on the File menu.
In this scenario, every time that you click an item in the program to view a Web page, Internet Explorer 7 opens a new window to display the Web page. You expect that the Web page to appear in the existing window.
Additionally, when you right-click an item in the program and then click New Window to open a Web page, Internet Explorer 7 displays the Web page in the most recently opened window. You expect Internet Explorer 7 to display the Web page in a new window.
These problems do not occur in Microsoft Internet Explorer 6.
CAUSE
These problems occur because the DDE handler in Internet Explorer 7 does not correctly handle DDE navigation commands.

After you append some characters in an HTML page text box in IE7, the original characters in the text box are replaced with the newly typed characters
Consider the following scenario on a Windows Vista-based, a Windows XP-based, or a Windows Server 2003-based computer that is running Windows Internet Explorer 7:
• In Internet Explorer 7, you open an HTML page that contains a text box.
• In the text box, you use the Japanese Input Method Editor (IME) to type some characters. Additionally, after you type the characters, you do not press ENTER for confirmation.
• You click anywhere out of the text box.
When you click anywhere out of the text box, the OnChange event occurs.
• In the text box, you type to append some new characters.
• You click anywhere out of the text box again.
In this scenario, the original characters in the text box are replaced with the characters that you append.
This problem occurs because the OnChange event is fired before IME composition is stopped. Therefore, IME receives incorrect information about the text range. This incorrect text range information causes IME to remove the original characters in the text box.
