It's not clear what you are saying. Are you saying that when Enter is pressed the cursor does not move to the covered field and show it OR are you saying that the cursor does move but the scroll bar does not OR are you saying that nothing happens and the cursor remains where it is even though you press Enter?
And what version are you using?
As per my latest experience with Forms 12c, scroll works. there is no issue.
Thanks. B is right, the cursor does move but the scroll bar does not, so I cant see the field where the cursor is.
By design, Forms will always attempt to bring the current item that has focus into view. If what you are saying is that the cursor is moving to a field that cannot be seen then either your code is moving the viewport after the cursor has moved or something else is wrong with your form. I recommend creating a new, simple form to see if you can reproduce the problem. Again, keep the form very simple and do not make too many changes or add a lot of code. If the test form works correctly then likely your failing form has code that is causing the behavior.
Again, exactly what Forms version are you using and what Java version on the user machine?
