Random "Parking Window" Errors

I'm getting the following error fairly often (but randomly), and I can't
figure out why it is happening. Any ideas?

The line of my code that the error comes from is this:

//m_ConfigurationForm is a form that is member variable of the object
that the code is in
DialogResult result = m_ConfigurationForm.ShowDialog(Form.ActiveForm);

I get a popup box with the following:

An unhandled exception of type 'System.ObjectDisposedException' occurred
in system.windows.forms.dll
Additional information: Cannot access a disposed object named
"ParkingWindow".

And the following exception, with stack trace:

System.ArgumentException: Item has already been added. Key in dictionary:
