ArcView 10.0 - How to read the Geoprocessing messages in ArcToolbox?

Hi,

I recently upgraded to ArcView 10.0 and I used to be able to read and follow the messages of ArcToolbox geoprocessing tools in a dedicated window attached to the bottom of ArcToolbox. Where is this window in ArcView 10.0 and how to switch it on?

Cheers
