There is a problem with fastframes. Whether you choose 2 framestores or 150 to convert to a flyer clip my amiga reboots everytime.
So as another test I redid the animation only this time I saved them as RGB and not Framestores and used the flyer script IFF2CLIP and this worked perfectly.
I have no way to know why Fastframes doesn't work and oh by the way, Join frames doesn't work either. It also keeps rebooting the amiga
