Hi and thanks for the update!
Everytime you attempt to save a project in a different folder than the original, Spriter warns you about it. That's ok, but it seems to have frozen as I can't click my way out of the warning popout screen.
*EDIT* By the way, I have another one:
I forgot to mention that everytime you delete a sprite, the sprite doesn't go away and you have to delete it again, which causes a previous frame to get deleted instead. (This one is pretty weird..)
