When using the new Linux GroupWise client I often find myself in need for a dictionary. If I write emails in the same language as the client operates in that's not a problem, but I have to write mails to customers in different languages. How can I easily change between two languages every time I write an email? (firefox does this very nicely with right-click in text entries->Languages and you can select language from a list of available languages)

And another issue: We are moving almost every employee over to the Linux client, but how do we configure the client so when somebody presses an email link (i.e. support@novell.com) in firefox they get a "new mail" window inside the GroupWise client with correct To-address? Evolution and every other email client I'm aware of can do this easily if you configure them as default mail handlers in firefox's configuration.
