Process.StandardInput.WriteLine not working under Vista?

[=?Utf-8?B?U3VydHVyWg==?=]

The following code used to work. It starts up notepad and types a few lines.
What am I doing wrong? I'm using VB.NET 2005 under Vista. It starts notepad
okay, but it can't 'type' into it.
'demonstrate "typing" into notepad
Dim psiProcessStartInfo As New ProcessStartInfo
With psiProcessStartInfo
.Arguments = "" 'command line arguments
.CreateNoWindow = False
.ErrorDialog = False
.FileName = "notepad.exe"
.LoadUserProfile = False
.RedirectStandardError = False
.RedirectStandardInput = True
.RedirectStandardOutput = False
.UseShellExecute = False 'this must be false for
input/output/error redirection
.WorkingDirectory = ""
End With
Using prc As Process = Process.Start(psiProcessStartInfo)
MsgBox("")
prc.StandardInput.WriteLine("This line added by ProcessMgmtDemo")
prc.StandardInput.WriteLine("This line added by ProcessMgmtDemo")
prc.StandardInput.WriteLine("This line added by ProcessMgmtDemo")
End Using

Why are you trying to open and manipulate Notepad instead of just
writing to a file and then opening it in Notepad?

Thanks,
