I've created custom template for Sharepoint 2007 by editing master page in _catalog/masterpage/defoult.master. Every thing seems to be fine except upload.aspx form of my Library. When I hit upload button this file opens up in default SP 2007 template. Anyone know how to change that and make _layouts/Upload.aspx open using my custom template? I can't modify anything in /_layouts/ as we are on corporate site.
