In SharePoint 2003, the destination field is being set with the full path, "http://server/doclib". In Office 2010, the destination field is relative "/doclib". There is a method that creates the full path from the pieces and this duplicates the host name to send the following "http://server/http://server/doclib"

The Office 2010 drag and drop functionality for Uploading multiple documents is not compatible with SharePoint 2003 and the older product will not be updated to accomodate this.
