I agree with Alan; you have to toggle the Visible properties of the ListBox AND the Container.

I make extensive use of Grids in Containers that I "hide/show"; unless I toggle .Visible at both levels, I run into problems also.

The less "complex" controls like TextBoxes and Labels in Containers seem to be less of a problem (compared to Grids, etc).

It may be a "bug"; on the other hand, I think it's more of a case of having to exercise more control once one starts doing more "exotic" things in VFP.

In particular, when using "multiple levels of controls" and "hidden controls", you have to now be more carefull about using "arbitrary" .Refresh(es); if you do it at "too high a level" (eg. Form or Page level), you may start to get "hidden" Controls "bleeding thru". Also, "hidden" Grids will "resync" their record sources/relations.
