Database with form to test the described behavior

Don't know if this is a bug for Base or Basic or UI. 

Open the attached database.
Allow executing macros.
Open the form.
There is a table control with a list box for "Position". This list box will be
refreshed every time the row has been changed. (There shouldn't a "Position" be
available for a "Thing", which is used by another "Thing".)
Click in first row on "Position".
Click in second row on "Postion".
"Position" in first row will disappear.
Click in third row on "Position".
"Position" in second row won't disappear, because the whole content of the
table control has been moved above while refreshing the list box.
Now move by scrollbar to the see first and second row. 
No "Position" would be shown for first row and second row …
