Exploded Views in SW2013

Here's my issue.....

I've made an exploded view of an assembly...just like I've done hundreds of time. RMB and hit "Collapse" and it works fine. However, when I want to explode it again, normally I would click "Exploded View" in the Assembly tab and it would explode, but with SW2013 it doesn't work. I now have to go to the "Configuration" tab, RMB on the "ExplView1", click "Edit feature" just to edit something on me Exploded view. Does anyone else have this problem? This is very annoying and never happened with SW2012. Could this be a bug?

Thanks.
