You can use the standard version or the debugger version of Adobe® Flash® Player as clients for your Flex applications. The debugger version of Flash Player can log output from the trace() global method as well as data services messages and custom log events.

You enable and disable logging and configure the location of the output file in the mm.cfg file. For more information on locating and editing the mm.cfg file, see Configuring the debugger version of Flash Player.

You can configure the standard version and the debugger version of Flash Player auto-update and other settings by using the mms.cfg file. This file is in the same directory as the mm.cfg file. For more information on auto-update, see the Flash Player documentation.
