Hi,

Thanks for your response. I was out of office for 2 weeks...
When starting the application, we are opening all the remote views containing the references tables. In the load time of a form, we are using the "USE remoteView AGAIN" and setting the rowSources for each combobox.
It seems working well most of the time. We have a client that have been experiencing some problems after a while. Some of the items are missing in the combobox and they have to exit and restart the application to correct the problem.
