Problems opening PDF Files

When I go to the Fidelity webside and open a PDF file I can only open the first document. After I close the 1st document and try to open a 2nd document, all I get is a black screen. I have to log off and come back in to see the 2nd document. It's almost like something is blocking my access. This just started recently, I never had this problem before. Has anyone else run into this? Fidelity tells me they haven't heard of anyone else having this difficulty. Thank you.
