Software

With Internet Explorer open, reset to the Default settings.
You did not mention which version of IE you are using. So...
If IE6 - go to Tools - Internet Options - Advanced and then click the Restore Defaults button.
If IE7 - Tools - Internet Options - Advanced and click the Restore Advanced Settings button (NOT the Reset button).
Then close all instances of IE, reopen and try again.

Also, if you are using IE7, try turning off it's built-in pop-up blocker. Tools - Pop-up Blocker - Turn Off Pop-up Blocker.

It may be that there is a problem with your IE plug-in for Acrobat Reader (.PDF files).

One other thing to try if you are unable to find what is blocking a PDF from opening on your end... when you get to the page that has the link "If a new window did not open for your download, please click here."... instead of left clicking it, try right clicking it and selecting 'Open in New Window.'


Please let me know if this helps.

Open Adobe (with the IE7 closed).
Go to Edit - Preferences - Internet (Catagory).
Uncheck the Display PDF in Browser.

I know it sounds counter intuitive, but this has alleviated a lot of our problems with displaying Banner PDFs.
