Rob,This may explain some of your other problems as well. StrataFrame does not keep connections open to the database at all. It is only open long enough to execute the query and then we explicitly close the connection. We are still in the process of getting our Oracle server restored (we rebuilt our server where Oracle previously resided), so I cannot immediately test this. But it sounds as though there is something else in the mix here.
What is your setup (OS, Service Packs, layout, etc)? Thanks.
