Thanks for your post.
We have only couple of reports about this behaviour and so far we are unable to re-produce the behaviour in-house which makes it difficult to solve.
Our engineers believe the issue could be environmental to the machine or GroupWise account as the Formativ works fine for some users but not for a specific user. It could be a bug in the GroupWise 3rd party plugin.
– Does the Formativ toolbar button works when you change the User B – View/Toolbar/Main ticked ON?
– Can you run the Applet from the User B GroupWise – Applets menu?
– Making sure the GroupWise View issue, does the Formativ toolbar button works when you change the User A – View/Toolbar/Main ticked OFF?
Look forward to hearing from you.
