The FldGrabFocus line should be redundant. When you call FrmSetFocus, that
routine itself will call FldGrabFocus. It's important to use the Frm call
because the form has a variable that tracks the current focus--necessary so
that the form can tell the field or table to release the focus if the form
loses/changes focus.
If FrmSetFocus isn't working for you, it's probably because you're calling
it at the wrong time. That is, you probably do set the focus to the field,
but then some other bit of code comes along and sets it to something else.
Tracking this down could be tricky, but I think if you set breakpoints in
your event loop and watch the event flow and which Frm calls get made,
you'll find it.
