source code and executable

click a button on the form, a thread is started, periodically calling Control.invoke.
On windows, the title of the form is updated every one second.
but on OS X, the title usually remain the same, unless I drag the window around or do something else to the window.

Environment: Windows 7->VMware Workstation 9->OS X 10.9

Comple: Visual Studio 2013 Update 4

Command Line: sudo mono WindowsApplication2.exe

Code:

Public Class Form1

    Delegate Sub UpdateTitle()
    Dim k As New UpdateTitle(Sub()
                                 Me.Text = Now.ToString
                             End Sub)

    Private Sub test()
        Do
            Me.Invoke(k)
            Threading.Thread.Sleep(1000)
        Loop
    End Sub

    Private Sub Button1_Click(sender As Object, e As EventArgs) Handles Button1.Click
        Dim t As New Threading.Thread(AddressOf test)
        t.Start()
    End Sub
End Class
