Hi Alan, It sounds like your Workspace Control settings might be taking over existing sessions. If you control WC from the Web Interface, try either disabling it or setting it to "disconnected sessions only" as a test. If your Web Interface allows users to customize, go to your Online Plug-in settings. Try disabling both "Logon Options" and "Reconnect Menu Options" within the "Reconnect Options". If that fixes your problem, you might be able to loosen it up a bit by setting both to "disconnected sessions only".

I'm just starting to look at upgrading the ICA client currently used on our estate from 10.2 to 12.1 and am foxed by this issue. Currently with the 10.2 client we just used PN (no PNA) and Web client. The web client is used by users with a PC and all our support functions and they all access the same web site URL. This site is configured for pass through authentication and the Management Console is configured for custom administrators using their normal (non-elevated) userids. PN is used by our higher level support functions to access individual servers and they can then log in using their elevated credentials. I also have a test site which requires authentication so that I can log on with one of my test accounts for any application testing as a standard user. All well and good. Clearly the 12.1 client doesn't have a PN component and I'm keen to move to a PNA environment anyway. Have installed the full 12.1 plug-in on a couple of test PCs and set up a PNA site and this all works well and I believe it will satisfy the vast majority of users and most of our support functions. The issue I have is with adnministrative access to published desktops. I have set up a.n.other site which requires authentication and when I log in using my administrator credentials I can see all the desktops that are published for administrators. Selecting one of the Desktops and it starts as expected. The problem comes when I connect to another Desktop (from a different server, with a different name etc.). The first Desktop disappears and log progresses on the second Desktop. Connection Centre and the Console shows two Desktops but only one is visible. This happens for all further Desktop connections. If I login locally as an Administrator then the PNA shows all Desktops and I can connect to each without them disappearing !!.
