Document classes and multiple scenes?

Hi!

I’m new to as3/flash, but got some programming experience in .net, so not a total newbie ;).

I’ve been searching the internet for how to use scenes in flash games, and from what I understand it got some problems? MY problem is that i cant really understand what the problem is and I cant find i “clean” explanation.

Some say you dont should use scenes in game development, some say you should?? Im confused.

Another thing that i dont understand quite is the document classes. Should i have one document class for every scene or one for all of them?

If i have 2 scenes with it’s own document classes, how do i switch between them?

Thanks for any reply.
