Fireworks is a kick@$$ program and all but there are two things wrong.
1. If you dont have money to spend you're not getting this prog.
2. Fireworks takes a lot of memory and RAM to run, so if your systems is extremely slow or even moderate its most likely your system will crash whenever you try to use Fireworks.
Any questions?
Photoshop is really all you need, or paintshop pro. Their both smaller, cheaper, and as effective as Fireworks.
