The only time the AniLab palette gave me problems was when I clicked on the "AnimationLab V5" checkbox in the "Tools / Customize" dialog; would hang the program. Activating the palette from the menu or toolbar always worked okay.
I keep the AniLab palette in the second monitor, in a “nest” of three palette columns within a main palette. I can view more info without having to click on a palette tab all the time.
