Because of some issues I am experiencing in my Captivate project, I needed to hide a number of slides. To my utter disappointment, I found that after I unhid these slides, my locked objects/buttons lost all their "On Success: Jump To Slide actions" and defaulted back to "Continue"
I would have grudgingly accepted this behavior, if those objects were not locked but I expect that regardless of dependencies, locked objects should never change!
In my opinion, if a dependency is lost than it is acceptable for the internal logic can default to "Continue". Even better, display a publishing message stating that object x's dependency no longer exists.
If you really feel this way, then you need to log a change request at this link:

Talking about it in a forum thread doesn't necessarily add it to the queue for any future version.
