Email Hyperlinks from PDF

I am having a problem with PDF documents that have hyperlinlked e-mail addresses in them. When clicking on the e-mail address it should open a new e-mail message in Notes. What I am seeing is two different things. Either Notes will open TWO new e-mail addresses and ONE web browser window OR Notes will open ONE new e-mail and TWO web browsers windows. I have tested this on multiple machines running Notes 8.0.1 and IE or Firefox. When I test it on a machine running Notes 7, everything works as expected.

Anyone have any ideas?
