Without scripting every field, if you have a data entry system with multiple fields, and you want to flag the user that he or she made a change but did not save before click "next" or "Previous" to go to another record... what would be the simplest method to check that the card was modified to then prompt the user "Do you want to save your changes?"
In the card script (or stack script, depending on how the stack is laid out), trap the "closefield" message, which is only sent when field content changes. Set a script local or global variable to true. Then on closecard, check the variable and ask to save if it's true. Then set the variable back to false.
The only catch here is that if any of your fields have closeField handlers, they'd need to pass the message so that the card could catch it.
