I am trying to use a poseball with two avatars....

A script can only hold PERMISSION_TRIGGER_ANIMATION for one person at a time.  If a second person activates it, the script loses the permission that the first person granted.  The animation may continue for the first person until it is interrupted by another animation, of course.  The other animation might be in an AO, if you hadn't turned the AO off, but it might also be triggered by any other action (standing, for example, or a typing animation or the animation in another scripted object) that has a higher priority.

But this just started...we have always done pictures together and never had an issue before until today ?

Then he's started wearing something new that triggers an animation, or maybe you have replaced some animations with others that have a lower priority, so they are more easily interrupted. It's really hard to guess much more than that without knowing how the poseballs were scripted. Generally speaking, though, poseballs are pretty primitive devices, easy to break.

Rolig's answer gives a clue as to why couples poseballs always come in pairs...a blue one for him, a pink one for you.  The colors are arbitrary, but the existence of two separate poseballs is not!  That way, each ball can contain the proper animation and script to run it.

I understand what you and rolig are saying...but why would this happen all of a sudden ? we have used the static poseballs for pictures many times on the same sim and they have been fine, but now this happens ? why ?

As I explained in my Permalink response to the same question, my guess is that he is wearing some new item that contains a higher priority anim, or that they have changed the anims in the poseball recently. He may in fact be wearing two AOs (one that he can see easily and another -- maybe the Firestorm built-in one? -- that he has forgotten about. Or maybe it's a high priority typing anim? Some of these things are not obvious and may appear unrelated to many residents.
