Access 2K Form Flickers

Several of my forms in Access 2000 flicker as I move from record to record. It stops when I move the mouse pointer over the form. I would think there’d be a way to prevent this, like triggering some code to run from the OnCurrent event, but I don’t have time to research the details.

The forms that do this have about 40 fields with some conditional formatting. I use them to view legacy data for debugging, so I will reject any solutions that require me to split the form into several forms.
