We have several GW8 users whos GroupWise clients don't properly open an attachment when double-clicked. Instead of the "Open" option, which will open the attachment in its respective application, the "View In New Window" option is selected, which is not what the user wants. I see no settings that allow the user to choose what double-clicking on an attachment does. Additionally, it happens to users only on certain machines and not others, which implies possibly a registry setting? On machines where this happens the "View in New Window" option is in bold when right-clicking and on machines where this doesn't happen the "Open" is in bold when right-clicking.
