Has anyone got any experience for this software in a Citrix environment? I am running Carpe Diem 3.5 on NT4 TSE SP6, MF 1.8 SP3, clients are build 6.20.779 and 6.20.986. The problem I am having is that intermittently, when a user clicks on a button on the screen, a totally different window appears (i.e. they click on a "add time entry" button, and the print setup box appears! Or they click the same button on a different session, and it aks if they are sure they want to abort the add!). This seems like a very strange problem to me. Has anyone ever come across something like this before - it doesn't happen when I run the app "fat" client. Any help greatly appreciated.
