new native winodow. when iam closing the native window i have to
remove all the text at movie clip and reset my application. My code
is:
stop();
var showalert:Boolean = true;
var goalert:Boolean = false;

Hi,
garbage system is different from olders versions, check
google.
Your problem is, that you are removing child from parent,
what do NOT have that child. Make sure, that you are calling
removeChild on the parent of child you want to remove. if you have
link to the object you want to delete, youse this:
curitem.parent.removeChild(curitem);
Good Luck :)
