The WHEN condition does not disable a control. It only prevents the control from getting focus. Use

SHOW GET ... ENABLE/DISABLE

>This button does not appear grayed-out when disabled. It is disabled, but the text color does not change. How do I do that?
>
>UPDATE: I should add that the Disabl_Color is not the color being displayed if the WHEN condition is false.
