Illegal seek offset on local cursors that are supposed to be exclusive and temporary, sounds like something interfering when vfp spools internal machinations to disk and expects the result to be its own exclusively. Apart from virus scanning, nosy apps like file monitors could do this. Where is the temp folder?
"... They ne'er cared for us
yet: suffer us to famish, and their store-houses
crammed with grain; make edicts for usury, to
support usurers; repeal daily any wholesome act
established against the rich, and provide more
piercing statutes daily, to chain up and restrain
the poor. If the wars eat us not up, they will; and
there's all the love they bear us."
-- Shakespeare: Coriolanus, Act 1, scene 1
