Showing the Restore button is the standard behavior of the Ajax clent. If you want to get back to AccessPoint, use the browser back button.
For your document chaining scenario, the user requires access to the inpatient & outpatient qvws so I don't think you can hide them from AP. Here's a couple of potential workarounds.
1. Put the URL to open enterprise.qvw on another web page. That is, don't use the AP.
2. Put the outpatient/inpatient qvws in another category. Have the use fiter by category on the AP so they only see the enterprise.qvw.
