Reply To: New Version of Document Opens Old Version

I honestly can't think what inside a document could cause that. Sounds very odd.

But a bigger question is: Why are you trying to copy and paste from the original document? What is wrong with the old, tried-and-true: Save-as-then-work-on-the-duplicate? Save As removes file bloating. I would probably do a save as, then strip out what I don't need anymore, then do another save as and be on my way. You could throw in an export-to-INX/IDML-and-open-that-file in there, but it's rarely necessary.
