The mentioned form is called by FrmInitForm and FrmDoDialog. Because
FrmInitForm is called before the EventHandle fucntion is assigned to it,
therefore FrmSetFocus in frmOpenEvent is never executed. I put the
FrmSetFocus right before calling to FrmDoDialog and the problem is solved.
Does this mean that nilEvent is sent to the form that has the cursor focus
only ?
