Closing Windows Issue on Dockable Panel??

Hello After effects insane coders ...

I've been trying to resolve this issue for quite some time now. I've tried everything possible, but I can not get any kind of feedback when "myWindow" is closed.

I need to be able to make modifications and save some changes when the user closes the main window or simply when it closes After Effects.

I need to be able to close all other windows that are open when closing "myWindow".

I'm trying this with the onClose function on line 89.

But the function returns no result.

I would also like to be able to save some data when the user closes After Effects, as I can not detect when "myWindow" is closed ... I also can not save this data.

Below is my complete code ...

I'm almost giving up...

If some charitable soul can help me, I thank you deeply ...

Thanks for all...
