[Laszlo-dev] ack! completely blank screen, compiling to swf9 with debug=true

[Sarah Allen]

So, I've been working away at fixing a/v bugs and compiling to swf8.   
I'm almost done with my most recent round of fixes, so I'm reviewing  
my changes and checking to make sure I didn't break swf9... whoops!  I  
get a completely blank screen, no errors, no warnings, no debugger.

Have you seen this before?  Is there any way to debug this aside from  
going back to a known state and re-applying my changes gradually until  
I find the line of code that breaks.

Thanks in advance for any advice,

Sarah
