mouseEnter/mouseExit event is triggering a screen jump ONLY when zoomed in?

Hi all:

First and foremost, to all the people who repeatedly post answers: you are truly rock stars in my book.  Learned so much from you all; deepest, deepest thanks.

I can't find anything online re: this issue, and BELIEVE me I've looked, so I'm going to do a detailed post with a detailed example.   If I do a good enough post, maybe that helps someone else out down the line.

Using LiveCycle Desiger to create a dynamic PDF.

Conditions

     When:

     1) A field has focus; (and)

     2) The end-user ZOOMS IN on the form;(and)

     3) The end-user decides to scroll away from the field with focus (so the field with focus is no longer visible on the screen but still technically has the focus)

The Issue:

     If the cursor happens to go over an object with mouseEnter or mouseExit code, Acrobat will jump the view back to the field with focus.

Practical example:

     1) End user opens a PDF and zooms in a little for easier reading.

     2) End user sets focus to a field at the top of the page to answer that question.

     3) End user decides to scroll down and see what other types of questions they have to answer, leaving the focus still in the top field;

     4) If the screen scrolling passes the cursor over an object with javascript in the mouseEnter or mouseExit event, Acrobat resets the view back up to the top of the page so

          the field with focus is visible again.

          Note: Even If the screen scrolling doesn't pass the cursor over an object with script in the mouseEnter or mouseExit event, if the end-user then moves the cursor over an

                    object with code in the mouseEnter or mouseExit event, Acrobat resets the view so the field with focus is visible again.

Additional Comments

     1) Object type doesn't seem to matter.  I tested it on additional field types in the attached and the jump seems to be triggered when code exists in the mouseEnter or mouseExit

          event and the field with focus is NOT visible on the screen.

     2) It doesn't appear to be a "top" or "bottom" of page issue.  Page 2 of the attached reverses the layout from "top-to-bottom" to "bottom-to-top" and the jump still occurs.

     3) It appears to be a Dynamic Form issue as I did a save as a Static PDF and the jump does NOT occur.

     4) Happens on both PC and Mac.

The attached is heavily noted and contains multiple buttons demonstrating the various conditions and what does or does not trigger the jump.

Thoughts?  I'm totally stumped.  A form level property that is trying to help???

Thanks in advance,

BR
