Different triggers for Normal and Hover states of the button

I may have been a little fuzzy in my answer.  All you need to do is to get rid of the trigger attached to the picture on the hover state. The problem is that you can't edit or delete it while editing states. You have to get the picture out of the state, delete the trigger, and replace it in the state,

1. if the picture you are using for Hover state is easy to reproduce, just delete the hover state, create a new hover state and paste a version of the picture that doesn't have a trigger.

2. If the picture you are using for Hover state is difficult to reproduce, edit the object's states. Copy the picture in Hover, and end editing. Paste the copied picture on the stage and delete the trigger. Copy the picture again, edit the object's states, delete the picture from Hover state, and paste the new one in its place. Be sure the X and Y values of the picture are both set to 0, so it lines up.

However you get rid of the unwanted trigger, from now on, you can copy the object, paste it to a new slide, and edit the trigger.
