I think this is an Access bug, and it's been driving my team crazy in an important business application, so I've tested and replicated this using the latest Northwind Developer edition 2.4, using a modified copy of frmOrderList.

frmOrderList is a Continuous Form. Modify the design to anchor some controls top right (e.g. from Order Date onwards, plus the controls in the header).
Open the form on a not-tiny monitor and enlarge or maximise the Access window. Click in the scrollbar on the right to navigate down and up the records.
Various problems can be seen, for example parts of the record details area can remain blank, or the right-hand columns simply don't update to show the correct information. The same problems occur when using Page Up and Page Down, but no problems are seen when using the mouse wheel to scroll.
If the form is kept very small so that no controls are being dynamically moved, all seems fine, but the moment controls are being moved by the anchoring the problems start.
Example images below.
This is showing a broken display with empty areas after scrolling up from the bottom:

This is showing the wrong data for the records after scrolling down:

I hope this can be fixed asap by the Access team, as it's really annoying and can even lead people to mis-read data completely as the wrong values can be displayed for a row.
