2. bug with mouseUp not passing through for event handling with on:send:to: target...
click all over the World and you will keep getting the dialog though you are not clicking the morph. #clickClient in MouseClickState holds the morph as the recipient morph for clicks.. rather than the modal dialog.. ( SimpleButtonMorph new extent: 80@60 ; label: 'test' ; on:#click send: #value to:[ UIManager default inform: 'test']; color: Color red) openInWorld.
