Is there an event that informs when Input window closes ?

[Mantadiver]

Step 1: EA added to chart
Step 2: User opens input window via F7 or right mouse click, "Expert Advisers", "Properties".
Step 3: User may make some changes.
Step 4: User presses "OK" to close the window and apply the changes.

Question: Is there an event or some way for the EA to know that the input window has been closed ?

I've searched but not found any clues yet.

Many thanks.

This is clearly a question for roar or miro. That question is advanced fxDreema knowledge!
