Scroll Wheel Hides(?) Record in Subform

[Degs29]

Somehow I didn't detect this when troubleshooting my database.

One of my users, upon entering data in a subform (in continuous view mode), used the scroll wheel and the record she had just completed disappeared. She then tried re-entering the information, but received the error message saying she had used duplicate values, etc. The info is still apparently there (and present in the table), but isn't displayed until we switch to a different record and back again. It's more a small annoyance than anything. It seems to only be a problem with forms using continuous view. Is there a way to change the function of the scroll wheel so it activates the scroll bar, rather than hiding records in continuous view?

Never encountered that behavior. Scroll wheel always manipulates the vertical scroll bar. Can't replicate the issue. If you want to provide db for analysis, follow instructions at bottom of my post.
