Hi David,

>If I create a collection of forms and I release one of the forms, the reference disappears automatically from the collection. So it behaves unlike other object references which would normally prevent the form unloading.
>Is this expected behaviour?

Yes - and I also do rely on it. It is as if the form's Release-Method does a RELEASE THIS, what removes the entire object and sets all references to this object to .Null.
