OOP learning

Hi everyone,

I’m just getting into object oriented programming and was thinking about buying Colin Moock’s book on the subject called “Actionscript 2”. Since AC 3.0 is out now, would it be better to get a book on this rather than AC 2, or since I’m a beginner with OOP do I need to get up to speed with version 2 before diving into AC 3.

Would really apppreciate any tips.

p.s if I should be learning AC 3 from the start, can you also recommend any good books?
