Check Box Built-in States
I am using a series of check boxes where learners check off statements that they think meet a certain criteria. This is not a quiz slide. I want to be able to make sure they check at least one box before proceeding to the answer display.
I am using a standard check box control. The state of these check boxes changes to "Selected" when clicked and when the checkmark displays in the box. However, when you click the check box a second time, the checkmark disappears, but the state does not change to Normal. It appears that the check boxes toggle to checked/unchecked, but the state of the control does not change once it has been selected the first time.
So, if a user clicks a few boxes, then unchecks them, the state is still recorded as "Selected."
I cannot find any reference on how the built-in button states work. Is there any information available?
