Hello
This definetly seems to be a problem with that specific mode for the last 3 buttons on the list. I will have to file a corrective action request so that the developers can have a look at this.
Meanwhile, I can suggest indicating the control focus in some other manner, like displaying a caption, changing control color, changing size of the control when clicked, etc.This way, the user would be aware when the button got focus, and you would not have to depend on the white outline to show up.
Im really sorry about any inconvienience this might have caused you. But with your feedback, we can look into fixing this problem for future versions.
Thank you
