I am aware that the documents were created a long time ago, with an earlier version of Word. I have never had any problems opening and editing those documents. There is no "convert" menu item in compatibility mode, only the viewing of the document. The problem
is that I have a document which has numerous addresses, which I use as a template to print out individual envelopes for specified addresses. I cannot access the menu to allow envelope printing. I can only access the "print" function, but that prints out all
the addresses. I only want to select one address and print out one envelope.
My issue is why has this occurred now, when the other day I could do what I wanted? Now all my documents show in compatibility mode. With no way to "convert" as you have indicated can be done.
