Contribute CS5 corrupting virtual server side includes

Hi

My template has a server side include as follows:

<!--#include virtual="/includes/vessels-breadcrumb.inc.asp" -->

When a new page is created from this template and published it corrupts the include as follows:

<!--#include ../../virtual="/includes/vessels-breadcrumb.inc.asp" -->

For some reason it is adding ../ for each folder from the root that the file is published in.  If the new file is published in the root of the Web site it is fine.

Anyone know why?

Thanks
