Hi Roger,
first of all, thanks for that extensive reply. Great.
Unfortunately i would like to make a pure actionscript project
without the mxml, because i wanna basically understand, how tings are
working on the basis, before i start developing with mxml as black-
box.
So could you perhaps also describe this "bootstrap" process or show
me a place, where i can find it myself?
That'd be great.
thanx in advance.
Sven
