    Webbrowser - not responding problem

    Hi!
    I have made a webbrowser who open automatically one by one many URLs from a big database but when it finds web pages like this one http://www.redstrand.com/TechBlog/po...te-Cursor.aspx my CPU usage is very high and I can't find a way to stop the webbrowser and move to the next URL from my data base. I tried with timer but is not working probably because of very high CPU usage. Even a button with WebBrowser1.Stop() won't work. Any idea please?

    To verify more easy try this simple code who must open first the bad URL and after completed to open www.google.com:

    Public Class Form1

    Private Sub WebBrowser1_DocumentCompleted(ByVal sender As System.Object, ByVal e As System.Windows.Forms.WebBrowserDocumentCompletedEventArgs) Handles WebBrowser1.DocumentCompleted
    Timer1.Enabled = False
    WebBrowser1.Navigate("http://www.google.com")
    End Sub

    Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
    Timer1.Interval = 40000
    Timer1.Enabled = True
    WebBrowser1.Navigate("http://www.redstrand.com/TechBlog/post/Template-Cursor.aspx")
    End Sub

    Private Sub Timer1_Tick(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Timer1.Tick
    WebBrowser1.Stop()
    WebBrowser1.Navigate("http://www.google.com")
    End Sub
    End Class

    This should have been posted in the .Net section.
    But until it is moved, others with very good knowledge of the webbrowser control may be able to answer. It appears it is nearly the same in VB6 as it is in .Net.
