I’ve just begun using OO5, previously stayed with OO3 (pro). I created a new document in OO5 and dragged a pdf into it. Then I saved the document. When I double-clicked the attachment to open it in Preview, I got this message:
Is this a known problem? I looked at the release notes and didn’t see anything.
You can avoid this problem by choosing “Save as file package” in the documents inspector.
Thanks! Didn’t even know that existed.
