I have installed, uninstalled Adobe Reader 10 and Internet Explorer. I have tried all the solutions listed in some other posts. PDF links will not open the files on some web sites, Fidelity.com in particular. I have reset IE8 Advanced Options and Advanced Options Reset, Created another Windows Administrative user, performed clean boot in Windows and run IE8 (no addons) from the accessory menu and unchecked the Display PDF in Browser box in preferences. None of these options have resulted in correcting the problem. Adobe Reader 10 works fine on the Fidelity web site in Firefox.
