I am trying to veiw my model in photoview preview.

     I have my model in the photoview preview and when I go to change the angle or plane I am looking at; the model will start to turn but then snap back to the original position it started at. It will also freeze in the middle of me turning it or me trying to have it snap to a different view. I just wanted to see if this is just a problem I am having or if anyone else is having it to.
