Open Only One Browser Window at a Time While Shopping
- Error states: "The application was unable to route the session back to the login page."
- The error occurs when the user has had more than one instance of Shop@UW open and attempts to continue shopping after closing or exiting shopping the extra browser windows.
- Since the user has actually logged out of the system when the extra windows were closed, the system has closed all sessions. The user must log into Shop@UW again to continue shopping.

Shop@UW Connection to Punch-out Supplier Web Sites:
Airgas, Dell, and EIS Office Solutions
With Chrome's recent upgrade, the browser now flags pages with insecure content. Shop@UW is able to successfully establish a connection and re-direct to the supplier's site; however, the user will notice a shield icon located on the far right side of the URL bar which indicates the page includes scripts from unauthenticated resources.
- Click on the shield icon.

- Click on the “Load unsafe script” text link.
- Content for the punch-out web site will load in the browser window.
