I typically cover this by actually opening the PDF in a new window. You can use JavaScript to do this, and have a noscript tag to cover the case where the user has javascript disabled (for accessibility). TIP: Use "target='_blank'" in your link, and it'll open in a new window.....

Comment on Re^2: (OT) Have to press BACK button twice in IE to get back from an HTML page to a PDF!
