The upgrade/installation should show the task bar by default. It would save the typical user a lot of trouble trying to figure out what was going on when the task bar disappears. It was not obvious - even a dialog message during the upgrade would have helped.
I, for one, do not use coherence mode and when the task bar disappeared I thought the problem was a compatibility issue with the new tools. When I de-installed the tools the task bar worked fine. Only after checking the forum did I see the note about the new setting.
