Creating Top Content for an Entity created from an External Table in ASP

Hey guys,

I've created an external table connection to a view in an external database. I've created the appropriate screens/blocks inside my asp page and everything works great. However my problem is when I search for records and click on the hyperlink to run the asp page to view the record it shows the My CRM top content and tabs. How can I control the top content and tabs for my custom external table entity. The name of the entity is RebateHeader. I created a new screen called RebateHeaderTopContent and then in my asp page called CRM.GetCustomEntityTopFrame("RebateHeader"). All that does is make the call to the asp page much longer to load (like 30 or more seconds) which I thought was weird but it doesn't change the top content. I don't necessarily need any top content (although it would be nice) but even if there is a way to tell crm not to load the top content and tabs that would be a win. Thanks in advance.
