i've just noticed something odd and I was wondering if someone knows why this is.
scenario, basic game - document class.
object 1 - has keypress to move it around
object 2 - start btn.
add both objects to stage.
click object 2 - remove it and listener... object 1's keypress doesn't kick in until you click the swf (in browser)
it sort of makes sense to me but I'm hoping someone has a more decisive explanation why this is.
