Version: 1.2.5 (using KDE 3.5.8) Installed from: Ubuntu Packages If there is a contact associated with a ToDo item, and that item is checked off (or edited) then a popup dialog appears asking if the person should be notified. An option to disable this popup is necessary, as it makes working with the ToDo component very frustrating.
Still reproducible on trunk r865573.
You can disable groupware communication though, or do you want an option to disable only for to-dos, but enable for events ?
