Lite 2.0 - Storing in sharedObject when program exits

[Doccie]

Hello, I'm creating a mobile application where, at one point, I want to save the current frame when the application closes.

I haven't tested it yet, but I assume there are two ways of closing the standalone player. Either by using a button in the application or by pressing the 'c'-key on your mobile.

Obviously, I know how to store information when the user closes the application by interacting with the button inside the application, but I want to know how I can save the frame location when the user closes the application by pressing the 'c' key.

The 'c' key is not supported by flash lite and cannot be remapped. It might be possible to continuously save the frame count, but I fear that will slow the cellphone.

Note: this question is related to Flash Lite 2.0 (flash mobile). I put it in here because I did not know where else to put it.
