Hover and Visited-States Trouble

Visited states:

from what I can tell, the selected state has the glow and when that object is selected the glow appears. If you selected a different visited object, the glow disappears on the previous and appears on the selected. So that appears to be working as designed. If you don't want a glow, you need to alter the selected state.

Hover states:

The hover state is a built-in state that will become active when the user mouses over the object. However, as you note, the visited state becomes the hover state when the user mouses over. This is expected behavior.

You could remove the pre-built hover state and use a trigger instead: change state of object to [new name] when user mousesover the object. With that trigger you can add a condition to not change. For example, you could use a t/f variable that tracks if the button was clicked and then use that variable's value to determine if the mouseover trigger is active or not.
