I use free tables

There is no corruption when I run the application in the server,
but tables become often corrupted when I run the same application over the network

Is there a suitable way to arranje code, to minimize data corruption while in a network?

I already set autosave as ON, assing flush after every INSERT command, and still that table
become corrupted, because Windows it says could not save the file do disk

Can be dataenviroment cursors being the cause ?
