I did a little further research, and my previous idea won't work. First off, I was wrong about the existence of the ParentEnabled property -- there are other "Parent" properties, but not Enabled.
Additionally, it appears that R:Base is manually disabling and enabling all the controls for you to work around an issue in Delphi in which contained controls don't display as "greyed out" when their container is disabled. You will have to manually disable the controls after enabling the panel. Remember, you can use wildcards in PROPERTY commands, so if you can reasonable add _DIS (for instance) to the component ids of the controls that need disabling, you can do PROPERTY %_DIS ENABLED 'FALSE' to get them all at once. -- Larry
