Curve Editor Is Confusing AF

I find that curve editor just crashes a lot and is slowwwwww still. I’ve given up using it. I use Maya or blender instead. Such a pity but it’s just not usable. Also, elsewhere in iClone the foot sliding tool still has many bugs and causes knee pops constantly. I wish they’d update it.
