      If a user has Adobe Acrobat installed, when they select to open a PDF file in Sakai(Resources/Lessons/Announcement attachment/etc), once the file opens in a new tab for Sakai, an option appears and asks them if they would like to open the file in Adobe Acrobat.  If the user selects that option, Acrobat launches with an error(attached).  When the user goes back to the Sakai window and attempts to navigate, they will be logged out and must log back in.


      I tested this using Chrome.  Once I had installed Acrobat, I had to restart Chrome and enable to Acrobat extension. 


      I'll attach a sample PDF file as well.
