Messenger like flash app in systemtray

My question is in english. Feel free to answer in danish.

Does anyone know the details with how to make an independent flash application so that it is saved in the programs folder and is possible to keep a process running that can be viewed and send messeges via the system tray.

Ok, that sounds complicated. Heres what I know.

Ive got a program ( MDM Zinc ) that takes myFlashApp.swf and creates a myFlashApp.setup file. The myFlashApp.setup installs the myFlashApp.exe in the program folder (or whereever the user chooses). The problem is that it only runs in the system tray when the program is visible and running. I want the user to be able to choose to keep an application process running while the program is not necessarily visible. Just like MSN messenger. This way, the user will be able to get messages from another remote user and message can be passed and shown above the system tray.

DOes anyone know how to make this happen or if there are other flash to application creators that can help? If this is not the right forum for this question, can anyone give me a reference to another? Even that deserves points!

Thanks
