new Form in new thread

Hi,
Below in comments is the list of controls that I have defined. The function DoOpenUser loads and shows a new Form. This process freezes the application for a while as the Form takes time to load. Hence I wish to load the form in a new Thread or Async. The Form adds a UserControl which has a WebBrowser control in it. Also another UserControl2 property needs to be set in UserControl1

Please help me with pointers as to how to do this in a : new thread/async – WebBrowser control initializes in STA?

//myGrid – datagrid
//MyForm – public partial class DialogForm : System.Windows.Forms.Form
//MyUserControl1 – – public partial class MyUserControl1 : System.Windows.Forms.UserControl
//MyUserControl1 contains a System.Windows.Forms.WebBrowser component whhich won’t initialize in an MTA
//MyUserControl2 – – public partial class MyUserControl2 : System.Windows.Forms.UserControl
private void DoOpenUser(string myGridRowID)
{
myGrid.Cursor = Cursors.WaitCursor;
MyForm myForm = new MyForm();
MyUserControl1 myUserControl1 = new MyUserControl1();
myForm.Controls.Add(myUserControl1);
myUserControl1.Dock = DockStyle.Fill;
myUserControl1.UserControl2 = this.myUserControl2;
myForm.Text = "New";
myForm.Icon = MyNamespace.Properties.Resources.icoUser1;
myUserControl1.GetUser(myGridRowID);
myGrid.Cursor = Cursors.Arrow;
myForm.Show();
}
