When I open an *.eml that has been saved outside of Groupwise 8.0.2, it opens through Groupwise as an editable email. I can change the TO, CC, From, Subject, attachments and the main body of text. I can even hit send and it will be sent through my email account, but with the original sender listed in the TO.
It also automatically saves itself in the Work in progress folder.

Why is it doing this and how can I stop it?
