Disappearing feature class?

I have a feature class sitting in a personal database (.mdb). The feature class displays fine at scales >= 1:500,000. But once zoomed in closer than that it disappears.
The layer properties show that the "Scale Range" has been set to "Show Layer at all scales"

what else can be causing this disappearing act?
