RedirectingStandardError is redirecting standard output also

[kebo]

Hey all,
I've create a console app that handles some pdf conversions for me. In this app I send some text to the console and if an error occurs, I send text to Console.Error...

'for console writes...
Console.WriteLine("Converting page " & pageNumber.ToString)
 
'for error writes...
 Console.Error.WriteLine("An error occur during the pdf page conversion.")

I am then running the console app from a windForm app with this code...

Private Function pdfToImg(pdfPath As String, destinationPath As String, pdfToImgAppPath As String) As String
 
        Dim returnErrString As String = ""
         Dim p As New Process
        With p.StartInfo
            .FileName = pdfToImgAppPath
            .Arguments = String.Format("{0} {1}", pdfPath, destinationPath)
            .RedirectStandardOutput = False
            .RedirectStandardError = True
            .UseShellExecute = False
        End With
        p.Start()
        p.WaitForExit(30000)
 
        If Not p.HasExited Then
            p.Kill()
            returnErrString = "An unknow error has occured in the pdf conversion. The process never ended."
        Else
            returnErrString = p.StandardError.ReadToEnd
        End If
        Return returnErrString
 
    End Function

My intent is have the standard output go to the console, but redirect the error so I can display and log it, However when I set RedirectStandardError=True, it is redirecting all output including the standard output which I want to remain in the console window.

Has anyone seen this behavior before and know how to resolve it?
thanks
