Broken Search in ArcMap and ArcCatalog 10.2

Hi,

I have noticed after installing ArcGIS for Desktop 10.2 i am not able to use the Search window.

It comes up when i click search under windows in arcmap and catalog. However it show up as blank with no area to put in a search query.

And when ever i click refresh a Microsoft .NET Framework error comes up.

Is this a bug in ArcGIS 10.2. or can someone help me fix this.

Thanks,

Rod
