I have a requirement to present the user the Workbox when logging into the sitecore administration interface. I've identified that this can be done by setting the user profile Start URL to /sitecore/shell/applications/workbox.aspx. This works - when the user logs in they get the workbox, but the Logoff link is missing from the top menu (which is there when you access the workbox via the Content Editor - but I notice not if you access it via the Menu item).
Is there any way of getting this Logoff button back, or adding a custom one?
