[Laszlo-dev] dependence on ExternalInterface in swf9

[Henry Minsky]

I was having super  weird trouble with running swf9 apps , until Don sentthat
changeset which fixed buildlfcdebug. You ought to try installing that patch
if he
hasn't checked it in yet. I was using "buildlfc" and "buildlfcdebug", and
the updated
LFCs were not showing up at all in my compiled apps.

Now the swf9 debug console seems to be working for me.
