>Ordinarily I'd say yes, but it may be different if you're using CITRIX. As all the sesssions are efffectively being run on the same server, the unlocking of records is not going to be as reliable as it would have been had the sessions been on individual PC's.

Thanks for the hints.

Great news on Citrix! My app is reading the C drive of the client, not the server, so I stick with my "installed" licences policy and assign an activation code to every single user. I don't need to go to "concurent" validation anymore...
