*The strange thing is that there are some other Delphi apps connecting to a
Windows 2000 FB 2.1.1 server (Superserver) that works OK from several thin
clients, while this one, connected to our new CentOS FB 2.1.3 server
(Classic), doesn't run if there are 5 users previously connected (the app
doesn't appear al double click).*
*The thin clients connect to the FB to the same IP address AND FROM THE SAME
ADDRESS, TOO.*
