Exactly. But I have a program set up to open pdfs and it opened with another program for the same thing.

This has never happened to me before and it puzzled me. I don't know if the failure comes from Word or from the OS.

That was the reason for the query but now I repeat the test on another Word file and it worked fine. However I would like to know what this behavior could be due to and is it something rare or has it happened to more users.

Regards
