VB.Net BalloonTipText显示为黑色矩形

Question

I have a strange problem, I have created a test form FrmTest . Added a NotifyIcon and added the code shown:

Public Class FrmTest
    Private Sub FrmTest_Load(sender As Object, e As EventArgs) Handles MyBase.Load
    End Sub

    Sub FormTest_Click(ByVal sender As Object, ByVal e As EventArgs) Handles Me.Click
        Call SetBalloonTip()
        NotifyIcon1.Visible = True
        NotifyIcon1.ShowBalloonTip(30000)    
    End Sub

    Private Sub SetBalloonTip()
        NotifyIcon1.Icon = SystemIcons.Exclamation
        NotifyIcon1.BalloonTipTitle = "Balloon Tip Title"
        NotifyIcon1.BalloonTipText = "Balloon Tip Text."
        NotifyIcon1.BalloonTipIcon = ToolTipIcon.Error    
    End Sub
End Class

When I click to make the balloon appear I get this:

I must be doing something obviously wrong but I am stumped!
