When using the confirmation dialogue in an application it does not behave as when used in widget.
on 920xt it does not have color on selected item (makes you think you selected opposite of your choice) and default answer is "NO"
on 630 and vivoactive you have to press your selection twice, first time the selection goes away and next time you click the empty space it works
To reproduce just use sample widget and turn it into app.

Johan
