This seems to be a fairly new wrinkle. Trying to view a PDF on a website from a link in Word opens a page full of gibberish. When you click the link in the Word document, a "Loading" progress bar appears at the bottom of the document frame, crawls slowly and then launches a browser full of crap code.

The same process occurs if you set Firefox as the default browser, but the PDF does open. And the same link will open in an email, or Pages, or in a PDF.

I've checked my Internet Plugins for conflicts or older versions, but there are none. Anyone else experience this or have any ideas?
