BUG: onbeforeunload May Not Fire When You Move from an XML Page (328807)

MORE INFORMATION

Put the following files on a Web server to demonstrate the workaround and the reproduction for each example. After you save all eight individual files, view the Start.htm Web page, and then follow the instructions to start the sample code. Replace Myserverdirectory in Test3.asp with the path that contains the Repro.xml and Repro.xsl files.
