By pass the popup on Activity Screen

Hi,

When we create new activity from leads screen, the popup window shows up to select the territories. The component/view of territories is

BTPARTNER/TerritorySelList

Now our requirement is NOT to show this popup. How to get rid of this popup window so that when we are coming from Lead screen to Activity screen - this popup window will not be displayed. We are fine without populating the territory field on activity screen.

Thanks,
