What could possibly be happened as End is executing that causes the exception

This is almost the same as a previous post that is still giving me a
problem, but with a different slant.
I can't seem to find out what is wrong.
My program crashes after it leaves an event handler.
It is an event that is raised by Net's ListBox.
The form handling the event, as described below, contains a UserControl that
inherits from ListBox but does not handle nor override the event in
question.
So the stack contains only the handler and Main.

What could possibly be happened as End is executing that causes the
exception?

Thanks


What I see during debugging is

when I press F11 at the End Sub statement

I get the following error message in a dialog box:

An unhandled exception of type 'System.Runtime.InteropServices.SEHException'
occurred in system.windows.forms.dll

Additional information: External component has thrown an exception.

and

Application.Run(New Formzz) is highlighted

ps
What does this External Component mean?
External in what sense?
