New Button on workspace vs New button on general reports

I have and add-in that has been developed to fill in some custom fields in the background.  It is correctly filling in the fields and working correctly.

In Nov'12 we are testing and have found an issue that I have not been able to correct.  When we open an existing contact with the add-in populated with data, the data shows correctly.  Then we click new from that workspace(contact), and the add-in data is transferred to the "new" contact that has blank data. 

I have checked that all the variable are not public, the custom fields are blank on the new contact, and even went one step further and put in a function that resets the add-in to 'zeros' whenever it detects a "data loaded' event.  Looking thru the add-in log it clearly shows that the zero functin is working as expected.  However the workspace add-in is still showing the values.

To test things further i opened a new contact from a report view, and the workspace shows the values as blank(as desired). 

To my question.  Is there a difference in the way the "New" button is handled on the workspace versus the report, and menu locations?  If so, how is that, so that I can capture the event and get my add-in to refresh with the 'zero' values I desire?

Please view attached document for steps I used to test and reproduce.

Thanks,
