Morphing problem, AP3 becomes unresponsive

Hello all –

I’m having a real hard time with morphing, especially the hints. Basically when I set up a morph everything is smooth and nice, but if I have to set hints to fix interpolation problems everything blows up. Setting the source hints works fine, but when I flip over to the destination hints and try to drag them to their new spots the program hangs, I lose control of the mouse and I have to change to another program, wait for a few minutes, then come back. It’s painful. Honestly I’ve done frame by frame to avoid the problem, believe it or not that’s faster sometimes! It’s really frustrating, I don’t know if it’s a software thing, mouse driver (Intuos tablet) or what. I’m running Mavericks.
