On a computer that is running Windows Internet Explorer 7, a relative URI such as “/X:/path/file.txt” in the context of an absolute file URI such as “file:///Y:/default.htm” will incorrectly resolve to the following:

file:///Y:/X:/path/file.txt

You expect the relative URI to resolve to the following:

file:///X:/path/file.txt

On a Windows Vista-based computer, you open a Web page by typing a File Uniform Resource Identifier (URI) in the in Windows Internet Explorer 7 Address bar. This File URI contains a query string. However, after the Web page opens, the query string disappears from the Address bar. Additionally, the query is not in the document.location object.

For example, if you open a Web page by typing file:///c:/test.htm?p=1 in the Address bar, the query string disappears from the Address bar after the Web page opens.

This problem also occurs if you run a command at a command prompt to open a Web page on one of the following computers:

• A Windows XP-based computer that has Internet Explorer 7 installed
• A Windows Server 2003-based computer that has Internet Explorer 7 installed

For example, this problem also occurs if you run the following command to open the Web page:

iexplore.exe file:///c:/test.htm?p=1

Consider the following scenario. You develop an application that hosts the WebBrowser control. Then, you move to a link in the WebBrowser control. In this scenario, you expect the BeforeNavigate2 event to be triggered before the target page is loaded. However, when you run this application on a Windows Vista-based computer, the BeforeNavigate2 event is not triggered when you move to a non-standard link.

Note: A non-standard link refers to a link that has special characters and whose URL does not start with http, with https, with ftp, or with other known protocols.

For example, the HREF tag of the link in question is one of the following:

• <a href="<ABCD>">
• <a href= "/?scid=abcd%7cab12ab3l">

Therefore, the BeforeNavigate2 event cannot be used in the application.

Note: This issue does not occur in Windows XP or in Windows Server 2003.

When you change an Internet shortcut file on a Windows Vista-based computer, and then you try to open the shortcut file in Windows Internet Explorer 7, the shortcut file does not link to the expected URL. This problem occurs if all the following conditions are true:

• The User Account Control (UAC) feature is turned on in Windows Vista.
• Protected mode is enabled in Internet Explorer 7.
• You are running an application that installs a global hook procedure by using the SetWindowsHookEx function.
• The Internet shortcut file is saved in the Desktop folder.
