PROBLEM: Pressing CTRL+SHIFT+ENTER to test your AIR movie in debug mode does not produce any results.
SOLUTION: What’s going on is that the Adobe AIR Debug Launcher did not shut down properly when you clicked the X (close gadget) on the AIR movie you were testing. Or, if your AIR app didn’t even have window chrome with a close gadget, you couldn’t shut the process down.
On a Windows system, open the Task Manager (CTRL+ALT+DEL) and click on the Processes tab. Find adl.exe and shut it down. Now you’ll be able to test your AIR app again without closing and relaunching the entire Flash IDE!
