The problem lies in the fact that Internet Explorer and Firefox are trying to protect us from Evil popups, but because the inbuilt popup blockers cannot discriminate between a good and bad popup, we are left document-less.
The Solution!
If a patron is having this problem then check for a new message bar below the address bar.
Click on the bar and choose Download File (as shown above).This will take you back to the Blackboard Vista class listing, just go back to the class with the document the patron wishes to open and click on the link to it again.
This is the window that should now come up.
Now the patron is free to choose what he or she would want to do with the document.
