Crash on closing application

Very strange issue: my application with some TChart components runs correctly unlessI try to close it, then (on closing application) I get an Access Violation (similar to dynamic array violation for pointing to empty memory address). It happnes only if I draw some extra series in my TChart components, if not the closing application runs without problems. It's very strange that at runtime, working with my app, I don't get any exception but only when I try to close it.

Hi, 

Please add more information, perhaps a sample application, sample code with which we can try and reproduce this issue. Different circumstances causes different issues.

Kind Regards, 
Scheldeman Pieter

can I send source code and executable file? Where?
