- Mouse down on button 1 in a ButtonSelectWidget; button 1 appears pressed
- While mouse is still down, move mouse over button 2; button 2's appearance does not change, button 1 still appears pressed
- Release mouse; button 1 stops being pressed, and button 2 is selected
The pressed state should move with you as you move your mouse, to reflect what's going to happen when you release the mouse.
