I just got this message popup:
Unhandled event loop exception
Java Heap Space
Flashbuilder then crashed on me talking about memory problems. I have 4 gigs, memory shouldn't be a problem unless the software is really borked. I know notepad/scite doesn't give me any type lag for files with over 50k lines of code.
Maybe that can help you guys fix the type lag that I've been complaining for about 2 years now.
I wish the devs would stop ignoring me.
