When I view my tasks in the summary, the system does not show her name as the Contact.  It will only show the contact name if it's association with the Contact Module, not the Lead Module.  See screenshot below. Although names are blurred to protect the innocent, you can clearly see that the name is not there.

This is clearly a bug that needs to be fixed for full functionality.  I also cannot believe that there is no way to add an account name to this view.  As a sales person, I need a quick and easy way to see what my to dos are and this lack of information makes it difficult.
