1. I found a bunch on Source Forge. The top ones are most popular. Good luck. http://sourceforge.net/search/?type_of_search=soft&words=create+flash+files
2. Hi, Your best bet is OpenLaszlo, but keep in mind that is not exactly as Adobe Flash Professional. (You first need installed Java SE) Also try: Ajax Animator -- This one is web based and it´s very complete. Flash Develop -- This is for programmers (No User Interface like Adobe´s one) but it´s very cool. Greetings
