I've faced this before too.
I've tried many different approaches but the most reliable way I've ever found of handling it is to rename the new PDF each time (e.g. adding the revision date into the filename) and update the link in the web page to point to the renamed PDF.
Works every time.

Then tell her to uncheck all three boxes (display in browser, allow fast, and allow speculative)
But I don't see how that would fix it
Thanks for that.
To shorten the post I left out that I successfully downloaded the pdf using the new name - so I know that you are correct.
The problem with that (as a solution) is the level of understanding of the user - and, more importantly, the desire for understanding.
These 5-10 MB documents change regularly (adding up to wasted space) and the name change would also have to go to the anchor tag which the user is reluctant to modify.
Any other ideas? (I hope)
Ideally I will move them to a content mgt solution so they don't have to use DW, and if there isn't a solution to this soon (that works for the user) I'm also going to have to change all the pdf's to sub pages (which fixes the problem... but you understand that I'd rather move their cheese the smallest distance possible ;-)
I guess my point was that I don't know of any other bulletproof way of guaranteeing that users will always download the new PDF every single time other than physically renaming the file and updating the link which points to it.
A CMS, where document versioning (including rollbacks) is automatic and user friendly since it's all handled by a database, seems like the natural next step here.
