Gmail - keeps downloading same new message every 5-10 mins

[Rathna-K]

Below is the vb.net code I am using. the OnNew Message fires for the same message over an over again (randomly 5 -15 mins gap). Is there something wrong in my code?
VB .NET:

Form Load:
If mClient.Supports("IDLE") Then
AddHandler mClient.NewMessage, AddressOf mcOnNewMessage
End If

Public Sub mcOnNewMessage(ByVal sender As Object, ByVal e As IdleMessageEventArgs)

       OnNewMessage(sender, e)
End Sub

Private Delegate Sub dOnNewMessage(ByVal sender As Object, ByVal e As IdleMessageEventArgs)

Public Sub OnNewMessage(ByVal sender As Object, ByVal e As IdleMessageEventArgs)

    If Me.InvokeRequired Then

        Me.Invoke(New dOnNewMessage(AddressOf OnNewMessage), sender, e)

        Exit Sub

    End If

    Try

        Dim m As MailMessage = sender.GetMessage(e.MessageUID)

        Log("New Mail From : " & m.From.Address.ToString & "Subject: " & m.Subject.ToString)

    Catch ex As Exception

        Log(ex.Message)

    End Try

End Sub

Some servers seem to send an additional EXISTS notification after each EXPUNGE notification. Not sure why they would do that, but I guess this is the problem.

I have pushed a new version that addresses this issue. Please try and see if it solves your problem.
