This does not show up on Adobe’s Web site yet but, as has been announced elsewhere, you can get the new Updater 1 for Fireworks CS3. You have to update through Fireworks by going to the Help menu and choosing “Updates”.
The update fixes several critical bugs including shadows not scaling correctly in 9 slice symbols as well as legacy bugs like the stray unwanted pixel bug around sharp vector nodes/anchors on a vector path. I’m not sure what else the updater fixes. According to Alan Musselman, the updater listed the fixes but I didn’t see it.
In any case, it’s very nice to see Adobe being so proactive with updates. Other updates released recently include patches for Version Cue and Bridge. Good going Adobe!
