Multiple icons open in tray bar

Question

I am working on a Windows application, and when I run this application, there are multiple icons appearing on the tray bar:

and when I mouse-over these icons, they disappear.

Does anybody have any idea why this is happening?

protected override void OnClosed(EventArgs e)
{
    try
    {
        notifyIcon1.Visible = false;
        notifyIcon1.Icon.Dispose();
        notifyIcon1.Dispose();
    }
    catch(Exception ex)
    {
    }
    base.OnClosed(e);
    Environment.Exit(0);
}

Either you're not cleaning up the icons yourself, or your application crashes for some reason and has no chance to clean up after itself. — J. Steen, Nov 10 '12 at 09:16
Unless you post any *relevant* and *concise* code, no-one is likely to be able to help you. — J. Steen, Nov 10 '12 at 09:23

@Mr_Green: You are drawing a conclusion rather quickly here: Just because something happened to you, too, doesn't make it a computer virus right away. There's a good chance that there is something wrong with the user code shown. — stakx - no longer contributing, Nov 10 '12 at 09:37
@GurbaxSinghBhangal: Why are you swallowing exceptions with an empty `catch {}` block? Given your very question, shouldn't you be *extremely* interested to see whether your `notifyIcon1` disposal steps raise an exception? — stakx - no longer contributing, Nov 10 '12 at 09:39

Here is how I close my system tray icon to bring up the full application in a program I wrote a while back:

NOTE: this fits well in an event handler in the code behind, hence this.Show() and this.Activate()

            NotifyIcon sysTrayIcon = sender as NotifyIcon;
            sysTrayIcon.Visible = false;
            this.WindowState = WindowState.Normal;
            this.Show();
            this.Activate();
