with the release of Fireworks CS5, some commands needed tweaking. Orange Commands 1.5 brings CS5 compatibility, some bug fixes, and a new command: Safe Flatten.
Safe Flatten (in the Commands » Effects menu) duplicates the current selection, flattens it, and hides the original. Fireworks is known to distort your symbols when they have complex vectors, something that kills their appearance when they are supposed to be pixel-perfect. This command fixes that problem.
