Emulate a client/server model using TCursors and libraries. Extract the 
data you want to private tables and use those in your forms. Whenever 
you need to update a "real" table use a tcursor.

It's a lot of work to begin with but once it's set up it's RAD.

But if you're going to do that, you may as well go all the way.
