We are getting reports that users sometimes cannot Copy and Paste. Yet to experience it and cannot reproduce. Users can't reproduce it either. Any one offer any suggestions on how to track down/troubleshoot or even somewhere to start looking. Citrix have an article on this but of course this is based around it never working vs. our very intermittent problem. Thanks Malcolm
