VB.Net BalloonTipText显示为黑色矩形

Question

我有一个奇怪的问题，我创建了一个测试表单FrmTest。添加了NotifyIcon并添加了显示的代码：

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

当我单击以显示气球时，出现以下提示：

我肯定做错了明​​显的事，但是我很沮丧！

没有什么可以说你做得很好的... 这就是Windows 10上气球提示的样子。祝您好运。
