I use Bib8 to link my references to PDF's. In the attachment-field I insert a relative path to the specific PDF. This worked just great: I could either read the PDF by clicking on the PDF-window or by clicking on the Acrobat Reader icon. However, with the last references I've added (my database contains 200 references right now) the PDF's are not accessible anymore. The PDF-window is empty (although there is an asterisk * visible) and when I click on the Acrobat reader icon nothing happens. I tried to use an absolute path instead of a relative path, but this doesn't make a difference. I am using release 20090119.
