The only way I can think of is to have a save routine in the form's LostFocus and a restore in the GotFocus. I think it will still be faster.

I have also noticed that the second and subsequent times that a form, which had a Dataenvironment, was opened it was much faster. Presumably FoxPro caches the cursors it creates, even when the AutoCloseTables property of the Dataenvironment is left at .T.

I'm afraid I cheat in my apps and in cases where speed is important, I restrict the users to one modal form at a time. They don't seem to notice loss of flexibility and have never complained. At least not about that, they seem more interested in performance.
