Printing portfolio - but only document for document ...

Hi there,
I am suffering the following difficulty: I received a pdf-portfolio which contains 10 different documents. For an unknown reason there is for me no possibility given to print them all at once. So I do have to initiate printing for every single document and sort it afterwords -- which isn't funny at all ...
In the online-help from Adobe I found the hint, that I should mark all the documents in the side bar at the left. But this doesn't work either. There doesn't appear the promised windows that asks if I want to print a single document or all that are marked.
Who can give me the answer what I am doing wrong?
Thanks a lot in advance!


Well then, it took a little while but eventually the problem has been solved!
I deinstalled the newest version of the reader and
installed the version 9.0.0.
The print-dialogue from now on appears exactly as should be, I can decide eather to print some or to print all of the included documents.
So it seams as if there exists a bug which does't cause trouble for numerically enough people to become mentioned.
Who found out this solution?:
