I've never used it, but it's supposed to be an "easy" version of Flash, and you can download a free trial. I'm pretty sure you can download a free of trial of Macromedia Flash too.
he's right MX isn't much of a difference from 5. I've used both for a while and MX 2002/2004 is still just a buggy and crashy as ver5. I especially love how the interface scrollbars in flash just disappear for no reason and often flash will hard crash on me for no reason causing me to lose hours worth of work. yeah, good times
