[flexcoders] Folding only works when you fold all your AS code

[Corey Smaller]

I cannot seem to fold specific functions, just the mx/Script
instantiation which of course folds all my AS code.  I have folding
enabled and it worked in earlier versions. anyone else having this
problem?  you are supposed to be able to click in the folding area to
the left of the function either + or - . may be a bug in the latest
release (I got the nightly build last week)
