How to find out items modified inside a Forms screen

Hi,

 We have an issue that we do not manage to solve on an Oracle Forms screen.

 Here is a short description :

- The screen is opened from the main menu

- We perform a search from a field and the screen is filled up with all the information related to the entry

- We just click on the "Next" button to go to the next screen, without any modification, and we get a pop-up "Data has been modified, do you want to save (Yes / No / Cancel) ?"

 Another thing is that :

- If I enter the form, perform the search and just exit the form, I do not have any pop-up
