Hi, Monique.

If you C5 on the way INTO a form, it's usually a blown cursor reference - controlsource's invalid. Quickly determine the problem by cutting the grid off (paste it to another form for safekeeping) and see if the form loads w/o errors. If the grid is not at fault, check all your views. Test them outside of the form, or put this is the form's Load() method.

SET STEP ON
DODEFAULT()

If you C5 when EXITING the application, it's frequently an object that doesn't fully destroy itself as a form's datasession is destroyed. *Make sure* methods where you write code call DODEFAULT() where needed by the framework, especially in Init(), Activate(), Destroy() methods. If you forget to DODEFAULT(), you're probably hosed.

Hope this helps.
