I guess I had smth like:

if (levelComplete)
{
	resultingChart.dataProvider = asse  *haven't finished typing here*
	break;
}

then I started to write a new line before that unfinished one

if (levelComplete)
{
	for each (var series:I*here I requested AC for an interface*)
	resultingChart.dataProvider = asse
	break;
}

Important notice (probably):

I have just noticed that in the same scope (method) I had definition:
var series:LineSeries;

Experienced it today on Mac OS X 10.6.8, FDT 4.5.2.1328 (32-bit).

No idea how to reproduce it, but it happened after I was right-clicking an ISO file in Flash Explorer and FDT went Not responding on it. Looked like it ate all the free memory as well (a leak?). I've also noticed the same lag on right-clicking the MP4 video files in Flash Explorer.

Missing resource error was logged right before the loop exception. Attaching this as well in case it's connected.

Steps to reproduce:
  1. put an ISO image file somewhere into the project tree in the Flash Explorer
  2. right click it
  3. FDT hangs and throws the event loop execution error once it returns from the Not responding state
