Icons on buttons not clickable

Andrew, I guess we've had different experiences and encountered different posts on the Forum.  🤷‍♀️ 

I'll try to clarify my  "Groups often misbehave when triggers are added, especially if you want to use built-in states" comment. 

I've seen a lot of Group-related problems in the Forum. Most often, the posts are by folks who want to use the Selected and/or Visited states to indicate what has been clicked. But, of course, a Group can't have states. So they add triggers to ensure that all the states will change. However, triggers often cause problems when they duplicate what happens automatically with built-in states.

So the problem isn't with triggers such as "jump to" or "show layer" that are supposed to run when a Group is clicked. Those work as expected. 

The potential problem comes from trying to ensure that all the objects in a Group will change to the appropriate states. Fortunately, how the Group's items automatically change to built-in states has improved over the years. But the last time I checked (admittedly, a few years ago), all the objects in a Group didn't automatically change exactly how one object does. 

Plus, I guess I just like having fewer items in the Timeline.

Well, one of the great things about Storyline is that there are different ways to accomplish the same things. My motto? Do what works for you as the developer—as long as it works for the end user. 😁
