   Hi Peter, thanks for your reply.

   Let me try some answers:

 >Are you using roaming profiles?
   No

 >Check out the Windows Event Viewer and see if there are any errors.
   No errors

 >Another common problem is the Terminal Services Licensing.
 >By default, it tries to automatically locate a licensing server, which 
can take time and fail. It is typically better to enter the DNS name of 
the license server.
My TS Licensing server is the same box as the Windows server running my 
applicatios, so I don't think there should be any delays in license 
checking ... unless the TL Server is really broken. But I would rule-out 
this possibility since the "bad" behavior is really unstable ... 
something the Thinlinc-ed application works, sometimes it doesn't.
    This is a test system, no other concurrent sessions, no other users 
connected.

 >If this doesn't help, it could be a problem with device redirection. 
For example, I think I've seen in the past that a non-working sound card 
can cause such an effect.
   How can I check that?

 >I assume that the "circle" before "Preparing your desktop" still moves?
   Correct, the circle turns.

   I attach two process listings, HTH:

 1. ps_1.txt
    Process list when everything is OK
    Then I try to start Firefox and it does get stuck

 2. ps_2.txt
    This is the new process list while Firefox is hanging

   Cheers,

                 Ezio
