<p>I have a user that keeps getting this error.  Is there a tool that does window handle counting that i can use to figure out why he keeps getting this error.</p>

<p>System.ComponentModel.Win32Exception: Error creating window handle.
   at System.Windows.Forms.NativeWindow.CreateHandle(CreateParams cp)
   at System.Windows.Forms.Control.CreateHandle()
   at System.Windows.Forms.Form.CreateHandle()
   at System.Windows.Forms.Control.get_Handle()
   at System.Windows.Forms.Form.ShowDialog(IWin32Window owner)</p>

Maybe this could help:
