My neighbor went to a web site that required something along the lines of Acrobat Reader Browser Integration plug-in or something like that, and she has the PDFViewer plug-in installed in her Internet Explorer 5 Plug-Ins folder. The site doesn't seem to allow her to download the pdf, only to view it online. I've only seen this on PCs so I 'm not sure how it works or if it works on a Mac. Please help.
