Thanks Andrew,

All the workstations and the server are set to never go to sleep. The problem occurs when the users are working in Adagio not in idle mode.

I did uninstall Avira antivirus for one client, will see how it goes. The think is we have the same antivirus for all the clients and most of them are in Adagio all day and they don't get Application Hang error.

I suspect a Windows update issue and since Restore Points wasn't enabled I was wandering if reinstalling the Adagio modules can do any good.
