Google Chrome [the very last update this last Saturday] works much better. Click left on the *.PDF and Google display its own PDF [very fast] and the Google PDF has the save option +++ just like Adobe ... gorgeous ! For the Mathcad work sheets: click left, bingo it shows the open work sheet in a blank "file sheet", then double click left on the Mathcad icon , it hen takes the time to open Mathcad again as a separate instance. The last Google update is hyper fast, as fast as the click.
IE6 at work, when I first responded, and IE8 at home; both do the same thing. Chrome, on the other hand does go immediately into the Save dialog, but I think there's a setting for that, which is asked the first time you click on a file link. My Firefox has a dialog box asking whether I want to open it or save it, and check box for making that decision automatic and permanent.
OK, Firefox is easy to deal with. Go to Tools|Options|Applications. Scroll down to "Winzip File" or whatever your association is, and select "Always ask" for the action, if that's what you want. At the minimum, you should at least check to see if it's set for "Save File"
