Hi Jim,

just another thought, maybe you could let the tablets work offline. That is when they log onto your system, copy the data locally (I think you can use Offline views), then disconnect, then have a timer or something that runs and tries to get a connection periodically to update the central database.

Just a thought.

>>>Our application, according to them, and ONLY on the wireless workstations, "gives an error message and just dies and we have to re-boot the system to get it going again". The error is that the polled table is no longer accessible and we surmise that the network connection has dropped. We also learned that they didn't know how to invoke/use "Task Manager", so that should help some.

>>>We are planning to upgrade their system to use our SQL Server version once it is ready with all new version updates. But I'm not so confident that our problems will disappear because of the polled table. Seems to me a connection is a connection and if the network is dropped the connection goes with it.

>>>Thanks in advance.
Frank.
