>Now that I got it to work, there is a side issue. The user can hit RETURN to cycle thru all of the controls on the form, textboxes mainly, but now I want to exclude this chkbox from getting the focus, I tried no default and also issue a RETURN .F in its WHEN event but it still gets executed.

Did you try to set TabStop = .f. on this checkbox ?

You can also put NODEFAULT in GotFocus event (and set focus to next control in sequence), but I think TabStop should do the trick.
