TAdvSmoothDock does not show items hints

With RadStudioXE3 and the last TMSComponents version, TAdvSmoothDock does not show the hint for the items.
I would like to hide the caption and show a brief description of the item when the mouse is over it, but i can not achieve this behaviour.
With OnItemHover I can show the caption of the item but I can not hide it when the mouse leave the item.
How could I show/hide the caption of the item being hovered while maintaining all others captions hide?
Thanks in advance.

Please forget the previous post.
It was a mistake I made in my own program. All function perfectly well.
I forced PermanentCaption=true in my code but I forgot it.
Sorry for the mistake.
Best Regards.
