Hi Gerard,

>Is there a way to automatically ‘enable’ the Save or Cancel button as soon as any field has been changed.

You may get a buffering or Field Rule solution, but I will give you a simple Form Deisgner approach:

Create a method called FieldValueChanged() that does your button changing. In the InteractiveChange for every data control, call the method.

Easy enough? Personally, I would just leave the buttons avaiable the whole time.
