Thank you. I was moved to attempt a more vigorous review of the issue and find that the problem resides on the newspaper's side. So as far as I am concerned, the issue is resolved. Access to the PDF file is via a link in a daily email. Today's PDF file is 28MB and takes forever to open in my PC's browser (both Chrome and IE8) with a sometime result, e.g. does not always open completely. My Windows XP/SP3 desktop is very capable so it does not appear to be the problem. In retrospect my iPad provides impressive performance because I can download a readable version of the PDF file, although without some pictures, in a reasonably quick space of time. I like the PDF because I can access the paper while traveling. I seem to be surrounded by iPads and iPhones in my family (everyone has at least one and half have both) and they all love them. Anyway, thanks for all the comments and help.
