Adobe Fireworks CS4 always crashing on quit?
We have acknowledged this issue in the past after release of Snow Leopard. There is work in progress for a new update for Fireworks CS4. There has been one patch released some time back which would have fixed many text alignment issues for you. Once this patch has been applied, the Fireworks CS4 version would read 10.0.3.011.
If you have not applied this patch, please download it via Adobe Fireworks support site. The product manager for Adobe Fireworks has released an official entry at the team blog announcing the work for a new update.
