There are two issues here:
1) When trying to click the Email button within the embedded Adobe Acrobat displaying the PDF, the email is merely the binary stream.
2) When trying to save the PDF, it sets the name to some variation of streampdf.
The potential issues could lie within our setting of the PDF source as the URL. Perhaps if we use some sort of object (or perhaps the adobe object) Acrobat will know what to do with it. Additionally, there is the potential that there is something in openoverlay causing the issue.
save functionality has been fixed (point #2)
