Microsoft Access can't save your changes to this bound OLE Object

Hi all,

I keep getting this error message whenever i open an embedded PDF in my
access form. it only says that i dont have permission to write to the record
in which the object is stored, or the record is locked by another user. I did
not invoke any protection, nor is this file shared with anyone, so this is
definately not right.

I am the creater and user of this database. I did not have this problem
before when i used office 2002, it is only after i got a new pc with office
2003.

Any help / advice would be greatly appreciated.
Thanks in advance.

Ray
