I have an MDI application.  One form is opened.  From there a report button can be clicked, which opens another child form.  currentReportSelection contains the new'ed up frmReport.  I have a problem when frmReport is closed.  Once the report button is clicked again, a disposed exception occurs on the reportForm.Show() line:

private void btnReports_Click(object sender, EventArgs e)
    frmReport reportForm = currentReportSelection;
    reportForm.MdiParent = this.MdiParent;
    reportForm.WindowState = System.Windows.Forms.FormWindowState.Maximized;


The exception is:
Cannot access a disposed object.
Object name: 'frmReport'.

It always works fine on the first click but there after, I get the exception.  

How can I fix this?
