Links and Bookmarks Glitch

I am using CorelDraw X5 to create a PDF that uses bookmarks and links to navigate.

Is the bookmarks and links funtion of CorelDraw just unusable or is it just me??

Problem 1: I spent ages creating a range of bookmarks all over the document and then when I save and reopen, all the book marks are gone. This I found can be solved by closing and reopening the file. However it seems stupid to have to open the file twice every time...

Problem 2: --The worst problem -- I carefully create all the links to my bookmarks, save the file, then publish the pdf. I find the resulting PDF has its links all jumbled up and not going to the right places! I check my CorelDraw file (twice) and somehow the links have all messed themselves up and are now pointing the wrong bookmarks!

Help! I don't want to go fixing all my links just to have them get jumbled again...
