VS 2010 Window won't show after minimizing to taskbar on Win 8.1

I'm having a strange problem. My windows form won't redisplay after minimizing it. When I try to redisplay the window from the taskbar all i get is a "ding" sound.

It's reproducible on my Windows 8.1 system, using VS 2010 and .Net 4.0. and have narrowed it down to a call to My.Computer.Clipboard.ContainsText during Application.Idle event. I've used this code in many projects on WinXP and it always worked fine.

I've tried adding the attribute

Code:

<UIPermission(SecurityAction.Assert, Clipboard:=UIPermissionClipboard.AllClipboard)>

to the top of the form and to the App_Idle method but it doesn't help so I assume I'm doing it wrong or using the wrong parameters.

VB.Net Code:

' Add a toolbar with 1 button to a form.
Public Class Form1
 
    Private Sub Form1_Load(sender As System.Object, e As System.EventArgs) Handles MyBase.Load
        AddHandler Application.Idle, AddressOf App_Idle
    End Sub
 
 
    Private Sub App_Idle(sender As Object, e As EventArgs)
        ' Windows 8.1 makes a ding sound and prevents the window from redisplaying when minimized.
        Me.ToolStripButton1.Enabled = My.Computer.Clipboard.ContainsText
    End Sub
 
End Class
