Thank you so much! I have spent DAYS trying to figure this out. I did not think about the GROUP issue.
FYI: Groups are useful when you want a bunch of objects to smoothly animate onto the screen. However, they are (to put it politely) "quirky" when used in interactions. That's why I promote what I call "introverted programming"— that is, avoiding Groups.
This link goes to a presentation I did a few years ago with Storyline tips and tricks. My segment about avoiding Groups starts at approximately 38:45 in the video.
