>I have a container which has an OptionGroup in it. When I set the visible property of the container to .F. the optiongroup is still visible. I was under the impressing that the container controled all its objects.

Just to follow on Davids comment - if the property window dialog shows the opg at the same tir as the container, the the opg is a form control.

To fix, select and cut the option group, then select the container and right click it. On the pop-up select edit, then drop the cut opg "in" the container.
