Well even though I implemented the Delegate step that they mention to set the value on the status bar for time elapsed, as soon as I take out the Application.DoEvents the form will report that it is not responding and if the user clicks on it they get the typical whited out form.

public void SetText(string text) {
    if (myControl.InvokeRequired) {
        // this runs on the foreign thread and causes the
        // invocation of this same method on the GUI thread
