Working with C# in .NET, I am trying to call IActiveScript.Close on my instance

Working with C# in .NET, I am trying to call IActiveScript.Close on my instance of the Windows Scripting host.

Since I am currently hunting memory leaks, I discovered that I did not call this Close method and tried to add the missing code. So I added a call to the Closemethod.

Unfortunately, when calling the Close method, a COM exception is thrown with E_UNEXPECTED as the error code.

Querying the script state of the engine before closing it, it returns SCRIPTSTATE_CONNECTED.

Question:

How can I gracefully call IActiveScript.Close without getting an exception thrown?

    To (partially) answer my own question:

    I finally managed to build a stand-alone test application where I successfully can call the IActiveScript.Close method and also have no memory leaks.
