Our commercial solutions support GroupWise 8. However, we have a Beta release of the Formativ 2.0.2 Frameworks available which fixes a Formativ Studio issue for GroupWise 8.0 and it support Vista.
Could you please send your Formativ Configuration information to Support (firstname.lastname@example.org). You can obtain the configuration by selecting Help | About Formativ… from the GroupWise main menu. When the About Formativ dialog appears, go to the Configuration tab and click the button Copy to clipboard.
