State not resetting

I am changing the state of an object when hovering over the object to indicate to the user that by clicking on the object they will access a lightbox slide.  Example:

"Alarm Zones" (initial state) changes to "Alarm Zones  >>" (new state) and is also displayed in orange type.  When the user clicks on the object, they they open the lightbox slide as required.  When they close the lightbox slide, the object on the original slide remains in the new state.  If the user moves to another slide, the states then reset as expected.

Anyone have any ideas how to reset the state on the original slide object when the lightbox slide closes?

Thanks
