Acrobat reader 7 only allows one file open!?!?!

Hi: I updated my Acrobat reader with YOU (Suse 9.1) the other day, and now I discover that it seems to only allow me to open one PDF at a time. Is there a way to fix it so that it can open multiple PDFs? Thanks. -- Good day! ________________________________________ Christopher R.
