If the endnote has a bug?

when i delete the record that has pdf ‘File’ Attachments, all the pdf Attachments in the library are gone.

i have tried from endnote X to X3. 

I want to know if it is a bug of  endnote.


I just tested EndnoteX3, on  a Windows XP machine, and only the PDF folder with the attachment(s) relating to that specific record got deleted.  The others are still there.
