No matter how powerful your computer might be, Adobe Fireworks has always sucked at handling large images and vector graphics. I don't know how you managed to achieve this, but that must have been a real pain. I can tell from experience. Nice work Jedi : ]
Yeah my friend its really hard but i have some tricks, first one fw works with mac much better .. 2. only firworks running on mac and if you save something with much of details vectors etc. try to zoom to x6400 ^^ it helps for me.. and hell yeah after one change save it, but yeah its really piss me off with more details fw gonna slower and slower.. I've already brought Fireworks to the limit.. if you have so much of details in fw in vectors, u can see so all bugs of fw lol
