Ok so I'm trying to do something I thought would be easy, but its not working.

I have Acrobat Pro.

I'm trying to embed a PDF thumbnail in a PDF file.

For discussion purposes (The main pdf is Doc A, Thumbnail pdf is Doc B)

All I want to happen is the user to click the thumbnail of Doc B, and it opens a separate PDF file, while still keeping open the current PDF Doc A.

I've tried this two ways so far, and each does not work how I want:

1st: I am able to have an image of a pdf thumbnail, and I can link to the PDF Doc B. I click the image and the PDF opens, and the original Doc A also stays open. Good so far.
However, upon sending the PDF to someone, the pdf thumbnail will not work. It gives an error "error locating file C:My Documents....". It appears it's trying to find the file located on my PC. Why cant I get that file to be part of the created PDF?

2. I added the thumbnail PDF as an attachment. It works, only problem is when they click the thumbnail, it opens the PDF, but the original document A is closed. So once I close the opened thumbnail Doc B, I need to open acrobat pro again.

This takes two seconds in MS Word using Insert->Object. Why is it such a pain in Adobe?
