Thanks for your reply.
I also got access violations when setting the caption of a button or editing properties of controls other than the list view while working directly in the object inspector.
Then suddenly these messages started to pop up in GroupWise when performing common tasks like opening a mail or pressing the ‘new mail’ button!
So I had to re-setup GroupWise (6.5.4) and Formativ this morning and I don’t know yet if this installation will be stable.
All in all it looks like programming in Formativ 2.0 made my GroupWise system crash (!) which is not very encouraging to me…
