Mark,

I modified the Valid() of the "Form with a valid check" to:

RETURN IIF( EMPTY( m.THIS.Value ), .T., 0 )

The behavior gets pretty ugly. Clicking on the "Form with a control" simply gives it focus, without the activate/deactivate sequence. If I click back on "Form with a valid check", it will no longer receive focus unless I click on the title bar. For a user, this could get pretty frustrating. I think Fabio's made a pretty good catch here.
