Open PDF doc from a form

[DSquared65]

I have several forms that open in datasheet view. In this view the field with embedded PDF documents shows only the words "Adobe Acrobat Document". This is what I wanted to happen, so that part is good. The problem comes in when opening any one of the embedded documents. One document will open, I can also close the document. BUT when I try to open a second document nothing happens. Nothing! The form must be closed and re-opened in order to open another document. I am not opening a second document while the first is open. The first document is closed. Any ideas? I am using Access 2007. I have done this same thing in previous version af Access and not had this problem.
