When using an Adobe® product that displays PDF files, you can display PDF files in Microsoft Internet Explorer in one of two ways:

1. -- Use the Adobe PDFViewer plug-in. Internet Explorer displays PDF files within its browser window.
2. -- Configure Internet Explorer to use the Adobe product as a helper application. PDF files appear within the Adobe product window.

By default Macintosh uses the second method. Your return is most likely behind your browser, on the desktop.

If you would like to change the default behavior, please refer to the Adobe® website for help.
