I have a VF page that calls a controller extension...when I place the VF page on a standard page and layout, it appears when the standard page is in view mode.  When the standard page goes to edit mode, the VF page section no longer renders.

I have tried exposing properties on the controller extension to set the "rendered" property of pageBlocks, but have not been successful.

Can someone explain the best way to show a VF page on a standard page when the standard page is in edit mode?

Thanks
