This is strange... Flex SDK 3.3.0.4852 is the latest stable build but it doesn't have these 2 packages: - flash.events - flash.net
I checked my SDK 3.0 (milestone build) and it does have those packages. However those packages do appear when I enable the "Include ADOBE AIR libraries" option. Are these packages accidentally got removed from Flex SDK 3.3.0.4852?? Or are they actually permanently got removed?
