I recently purchased Studio MX 2004 so I was trying out the flash extensions that came with it and I am very disappointed with the TextFX extension. The load times on it are horendous. Everytime you change something you need to click preview to see it. To it takes about 10 seconds to load the preview each time. Using the TextFX extension is a very slow and somewhat tedious process. And when you cancel out of it it takes a good 30-60 seconds of loading to go back to flash.
I’m pretty happy with the other extensions though. The pixel FX extension is esspecially useful and loading times are pretty much non-exsistant. I no longer have to import my images from fireworks if I need text blured or beveled or whatever I might need.
