Timing of item entry seems to be affecting the state of an object.

Object A is timed to appear 10 secs into the slide.

The state of Object A is changed to hidden when the state of Object B is changed to visited. Object B moves the learner away from this slide.

Upon returning to the slide Object A is visible again (I have changed the slide properties to "Resumed Saved State")

However, if I have object A appearing at the beginning of the timeline and not 10 seconds into the slide, it behaves as I want it to, i.e. object A is hidden when object B is visited and when the learner returns to the slide object A still remains hidden.

It appears that the timing of when object A initially appears is having an affect on the state of object A and I cannot understand the logic of why this is happening.
