title: How to rebuild the Visual Studio Toolbox?
body: <p>The toolbox in Visual Studio Professional 2008 has somehow ended up with 12 instances of each control.  They are just the standard controls, no third party controls, and I have no third party plugins.</p>
  
  <p>Is there a way to rebuild the toolbox to correct this issue with the dupes?  I've been living with it for a while, but it's pretty annoying.</p>
