SWfX, by Wildform (www.wildform.com) is an inexpensive, easy to use, text animation software that outputs directly to swf. Does exactly what it is supposed to and comes with literally hundreds of effects to shoose from. Although their website says OS X compatibility will appear soon, the app is carbonized and works well under X (much better than under 9 in fact).
Unfortunately, and this is a HUGE drawback....the software requires an internet connection to function. On install, it verifies your serial number and will not install without a connection. It appears it does the same when you attempt to launch it. I can notuse the app on my laptop because it is not connected to the internet most of the time. This makes an otherwise nioce peice of software useless and a waste of money.
I am waiting to hear back from their tech support to see if there is a work around...I doubt there is. I understand companies'desire to protect their interests, but this time it is directly at the expense of a paying customer's ability to get work done. Think twice before purchasing this.
