Pressing deadline and unstable flash debugger

I’m having problems with flash debugging on Mac OS. It crashed at various points regardless if I’m using the projector debugger or browser plugin (regardless of browser).

The only common denominator I see is that a method seemingly in the debugging code is causing a security sandbox violation with localhost, and then everything crashes.

I’ve googled this to no avail, if anyone can help it’s greatly appreciated.

P.S. Tried both 9 and 10 debuggers
