Well... I've made it thus far, but I believe it's time for me to upgrade from Flash MX 2004.
The main reason being Flash MX 2004 doesn't work quite right with Vista. However, I have it up and running on Vista due to my wonderful computer knowledge, but it crashes constantly and I've gotten fed up.

Besides, CS3 has a bunch of cool features! I want my drawings to glow! GLOW! You can't do that with MX 2004! Incredible!
