When I try to debug a flex application, debugging doesn't work.
I've got the debug player installed and playerversion.com says that I use the WIN 11,4,402,287 (Debug player).
After terminating the app, my IDEA console says:
Adobe fdb (Flash Player Debugger) [build 21328]

Waiting for Player to connect
Failed to connect; session timed out.
1. you compiled your Flash movie with debugging on, and
2. you are running the Debugger version of the Flash Player.
Make sure that your compiler options are not overridden from somewhere else. Just a wild guess.
