Have you tried setting the constantmask to true? I make gif animations with Fireworks all the time and usually I have to set the constantmask to true to avoid glitches in the display. See the RunRev dictionary for an explanation. I've never tried unoptimizing. If it works to solve your problem, let us know!
In Fireworks, using alpha transparency means using the transparent the canvas color (background) as the transparent element. Index transparency means you get to choose which color will be transparent; it defaults to the canvas color. Using Fireworks' animated symbols instead of copying objects will result in smaller, and maybe better, animations.
