Launching TelnetCE from another application freezes after close.

WM6.5, Motorola MC9190

I have a basic .Net app as follows which launches TelnetCE.exe as follows:

Public Class Form1    Public Sub New()        ' This call is required by the Windows Form Designer.        InitializeComponent()        ' Add any initialization after the InitializeComponent() call.    End Sub    Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click        Dim app As New Process        app.StartInfo.FileName = "\Program Files\Wavelink\TelnetCE\TelnetCE.exe"        app.Start()        app.WaitForExit()        Beep()    End Sub    Private Sub Button2_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button2.Click        Me.Close()    End Sub
End Class

Launching TelnetCE.exe and then exiting it the first time works fine, however if i try to launch TelnetCE.exe again, quit the application or do anything else the device freezes when another window is displayed/changed (such as when TelnetCE.exe is relaunched) or the applications window is closed.

The above application is a very baisc one I created to diagnose this problem with a more complex application.

Thanks
