TabStrip not firing VisibleChanged event on leaving tab

Folks:

If I observe the VisibleChanged event on a control on a tabstrip page, it fires when the tab is selected. However, when a different tab is selected, the VisibleChanged event does not fire, even though the Visible property is being changed to false.

You might want to verify whether you're firing the VisibleChanged event on the page controls when a tab goes hidden.

Thanks!
