Hi,
on adding subscribers to new issue of newsletter:
1. Clicked on "Add subscriber" --> Dialog (A) opened
3. Selected (•) Search users (if of importance)
3! Clicked on [Search] --> Another dialog (B) opened, full IE window with toolbars, showing user list
4. Selecting user
5. Click [Add subscriber] --> dialog (B) closes --> no refresh of Newsletter property page
6. Manually closing dialog (A)
7. Manually refreshing Newsletter property page --> new subsrciber shows as added

Looks like wrong target in form of dialog (A)
