Selected state deselecting when I move my mouse

Hi Iffaf. As you'll see in the attached copy of your project file, I disabled all the state change triggers as these were performing the same actions that Storyline's built-in or default states perform. That is to say, if you create a Hover state for an object, then there is no need to create a trigger telling Storyline that the Hover state should be applied to that object in the case of a mouse over (if you want the object to change to the Hover state by some other action...like when the user clicks another object...then yes, such a trigger is needed). The same goes for the Selected state: Once created, Storyline doesn't need a dedicated trigger to have the object change to Selected when it is clicked.
