I saw some where today (don't ask where, not sure if I can find it again) that this feature was turned off. It has something to do with the ones that were using animated items, not all signatures were and I understand this, and they were bothering/hurting a lot of the people that have vision problems. I believe that the signatures fall into this category. I hope I explained it. Will have to try and find where this was stated and let you know.
OK, found where Patrice mentioned this in another thread. Here is the link. Hope this helps.

Scroll down about half way down the page. She talks about it there.
It is also stated in the General Quilting Board Community Rules.
