Are you using some filtered data on your grid ?

If you have VFP9, you can set the property "Optimize" of your grid to .T.

>When I attempt to scroll through the records in the grid using the scroll bar or up/down arrows records begin to disappear. It begins to happen when I scroll down past the last visible record causing the grid to scroll down. If I click on where the record used to be the record becomes visible again but I'm not sure what is causing it to disappear in the first place.
