Troubleshooting
Problem
User authenticates to Citrix website (Citrix Storefront). User clicks on Citrix published application, to launch Controller product. The Controller client launches and appears, but the entire published application is completely black. It is therefore impossible to use it. Problem appears intermittent. - This is because the problem only affects users who re-attach to old *disconnected* sessions.
