VB.net web浏览器中的奇怪错误

我正在vb.net上创建一个应用程序，其中我正在使用web浏览器。代码运行良好，但每次打开应用程序时都会弹出一些窗口

这是弹出窗口：

如何删除此脚本错误。下面是我的代码：

Imports System.Text

Public Class Form4


    Private Sub btnMapIt_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnMapIt.Click

        Try
            Dim street As String = String.Empty
            Dim city As String = String.Empty
            Dim state As String = String.Empty
            Dim zip As String = String.Empty

            Dim queryAddress As New StringBuilder()
            queryAddress.Append("http://maps.google.com/maps?q=")
            queryAddress.Append(TextBox1.Text)

            webBrowser1.Navigate(queryAddress.ToString())

        Catch ex As Exception

            MessageBox.Show(ex.Message.ToString(), "Unable to Retrieve Map")

        End Try

    End Sub

    Private Sub Panel1_Paint(ByVal sender As System.Object, ByVal e As System.Windows.Forms.PaintEventArgs) Handles Panel1.Paint
        Try
            TextBox1.Text = Form10.TextBox6.Text
            'txtStreet.Text = TextBox1.Text
        Catch ex As Exception
            MsgBox("Welcome to Google Maps", MsgBoxStyle.Information)
        End Try

    End Sub


End Class
