Not working with FireFox
If you use this code:
protected void btnSubmitAsync_Click(object sender, EventArgs e){
//beep .. this is my modification
System.Media.SystemSounds.Beep.Play();
// simulate load on the web server for 2 seconds.
System.Threading.Thread.Sleep(2000);
// set textbox to the current date/time so we can verify things are working correctly.
txtDateSubmitAsync.Text = DateTime.Now.ToString();
}
When you make double clik to btnSubmitAsync button, you can hear, that FireFox post it twice.
Any idea? I have FireFox version .0.11. In IE works good.
