How to turn off the debug player?

[Barry Gold]

I followed the instructions in Gassner's book: _Adobe Flash Builder 4 
and Flex 4 Bible_, and installed the debug version of the Flash player.

But there are a lot of flash movies on the web with errors.  I'm tired 
of being told about all of them.  Is there a way to turn the debugging 
player off, then turn it on when I want to test my game?
