We have tested sites with both different behaviours on users and in most cases if the PDF would open in the same window the inexperienced users would accidentally close the window and as a result lose the website they were working with.
It seems to be already in the users' minds that a different page (e.g. PDF file or a third-party website) will open in a new window. So, very often without even thinking much about it they close the window once they are done. And to lose your point in a website is very frustrating, in particular for inexperienced users: they have to start all over again, open a new browser window, might even have to search in Google for the site again and find their prior position in your website. I wish it was different and we could train the users to learn to use their options, but I think this will be very difficult. Opening links in new browser windows has been around for such a long time, most users have learned to accept it as a standard and in fact rely on this happening. So for my perspective: definitely open PDFs and other such documents in new windows (allows modem users to stop the download at any time and prevents users from accidentally closing their current website). Cheers, Andreas. ________________________________ From: Drake, Ted C.

What is the general feeling towards having pdf and other non-html documents open in a new window? I personally find it annoying to open a pdf document in the native window and having to wait for the reader to load. I usually right-click and open in a new window. However, I know some people expect that to happen and could lose their place if a bunch of windows are opened. I would use the javascript approach to avoid using target="_blank". This should avoid the complications of having PDA devices or screen readers attempting to open multiple windows. So, I told my co-workers that I would throw this out to the standards community. Try to ignore any bias I may have. I would appreciate any honest feedback about whether we should open new windows for .pdf, .doc, .ppt, xls, .visio, or .whatever.
