A method I've often used to get around this kind of processor hogging is
to
set it up that only, say, 10 stars are animating at any one time (i.e.
only
10 have onEnterFrame handlers set or even better, following Weyert's
suggestion, update only 10 at a time using a single onEnterFrame handler).
As with Weyert's suggestion, the speeds that each star animates is random
and, as each star finishes it's cycle, you randomly select another star to
animate through one 'twinkle' cycle. I find this approach gives a really
natural feel to the effect as well.
I'd also echo Scott's observation that it could well be the _alpha
blending.
Flash gets tired really quickly when you give it alpha calculations and,
the
bigger the area of the screen it is making alpha calculations on, the
quicker it gets tired!
