In general, I really like the docking environment in ArcGIS 10. As I was showing off ArcGIS 10 to some of my end-users, I couldn't get the toolbar docked to the left of the map and to the right of the table of contents (TOC). Am I missing something here? I want to configure like ArcMap 9.3.1:

I think as a workaround, end users can dock the toolbar to the left of the TOC, and auto-hide the TOC(personally, I will do this). Or they can dock the TOC to the right of the map (and maybe also auto hide the TOC).
