End Google Ads 201810 - BS.net 01 --> I have a simple C#-(Windows-)Application. The Main-Form has two COM-Members. Working with this variables is ok, everything works as expected. When i close the application by the menu, i call Close() in the event-handler and everything is ok, but when i close by systemmenu or alt-f4 i got a com-leak. What is the reason, what is missing ?
