Moving to 9.2 OE fixed this issue.

Bob,

Interestingly I spoke with their IT support who initially looked at the problem and he indicated that he noticed that Adagio PDF was missing on the workstation and the event viewer reported a "faulty module" error on OEWIN and listed GDI32.Full.DLL as a bad DLL.

He reinstalled Adagio PDF but this did not make a difference in the ability to email.
