Metaframe Published Apps

I currently have 2 metaframe box's. Each of them has published applications. I have written a specific .ica file for each app then call them from a locally resident web page, this works wonderfully. My problems is that we have to enable disconnects for the ica connections. The problem is then when the user closes the application and not the session, all they will see is the blue server desktop. They can then close it, however when they reconnect to the server it then reconnects them to their previous session and thus the plain blue windows desktop...?? I think that it is functioning as intended however my boss feels that I need to fix this... ;-( any suggestions?
