Switch back when released

Displays the first picture all the time except when the user clicks the button. Displays the second picture until the mouse button is released. This mode allows you to create an action button with a different picture for each state (idle and clicked). You can use this mode to create a 3D effect or display any picture that depicts the action of the button.

Use Last frame as disabled

Enables setting the last thumbnail as the one to display when the button is disabled. The thumbnail used when the button is disabled is processed separately by 4D: when you combine this option with "Switch Continuously" and "Loop Back to First Frame", the last picture is excluded from the sequence associated with the button and only appears when it is disabled.
