Adobe® Flash® CS4 Professional software includes an integrated debugger. To use this feature, you need to use debug-enabled versions of the Adobe® Flash® Player runtime. The debug versions of Flash Player are identical to the non-debug-enabled (release) versions, except that the debug versions contain additional code to communicate with Flash CS4 Professional.
