If I export only some selected pages, hyperlinks to documents on HDD (other ones
not tested) will be broken after first unexported page.
"2.4.1  Multilingual version English UI WIN XP: [680m17(Build9310)]"
"Ooo 3.1.1 WIN XP DE[OOO310m19 (Build 9420)]"
"Ooo-Dev 3.3 multilingual version English UI WIN XP: [DEV300m84 (Build 9512)]"
My settings (3.3 Dev):
General: Range selected pages, JPG 85%, 300DPI, General all unchecked
Initial View: Bookmarks + page, Open on p. 1, Magn. Fit in Window, Page layour
default, 
UI: Display Document title, Bookmarks all levels, 
Links: Relative, Cross document default

Steps to reproduce:
0. Download and unzip test kit
1. Open sample.ods
2. Menu 'File -> Export to PDF -> Select Pages "1,2,4,5,6" ->  <export>
3. Insert new file name <ok>
   PDF will be created
4. Open your new PDF with AR or Foxit Reader
5. Go to Page 2
6. Move mouse Pointer to "Funktionsbeschreibung ..."
   Mouse pointer changes to link click hand as expected, hyperlink can be 
   clicked
7. Go to Page 3
   Move mouse Pointer to "MA" under Heading "7) ...) (or any other one)
   Expected: Mouse pointer changes to link click hand a, hyperlink can be 
             clicked
   Actual:  Mouse pointer remains as it is, hyperlink can NOT be 
             clicked

Problem does not appear if I select "export all pages" or when I select "pages
1,2,3,4,5,6". 

That's serious, I will get some more grey hear when I think about lots of
documents with that damage I sent to my customers ...
