>This is a case where subclassing of your controls will simplify the work substantitally! All you'd need then would be to add a form method to handle the recalculation and then add the call to that method to textbox (and edit box etc.) base classes.

>If you have several forms that use the same form and textbox classes, just default the form method to 'return .t.' except in the one form that needs recalculations.
