Bizarre behavior in VFP6sp5. On testing a form using a setfocus within a lostfocus event (to skip some boxes in the tab path) everthing works fine. When the form is run within the production environment it becomes the third form in a stack and fails the setfocus. The error is the usual 'Cannot call setfocus from within a When, Valid, RangeHigh or RangeLow event'. This is WITHIN a LOSTFOCUS event - the recomended location. Do any of you fine people out there know of a solution for this? What could be causing VFP to see this normal procedure as an error?

Thanks in advance.
