Using Grid or Row to layout controls inside Manipulate conflicting with Delimiter showing up?

I noticed that when I use Grid[] to help me layout controls on Manipulate, 
then follow that by Delimiter to add a straight line, then the Delimiter 
line will NOT show up.

When I remove Grid, the Delimiter will work.

Any idea of a work around? Is this documented? Ami doing something wrong?

------ no Delimiter ----
Manipulate[Text["test"],
  Grid[{{Control[{{a, 0.1, "a"}, 0, 1, 0.01}]}}], Delimiter,
  Control[{{b, 50, "b"}, 0.1, 100}]]

--- Delimiter OK -----
Manipulate[Text["test"], Control[{{a, 0.1, "a"}, 0, 1, 0.01}],
  Delimiter, Control[{{b, 50, "b"}, 0.1, 100}]]

btw, not just GRID, but also ROW has this side effect:

Manipulate[Text["test"],
 Row[{Control[{{a, 0.1, "a"}, 0, 1, 0.01}]}], Delimiter,
  Control[{{b, 50, "b"}, 0.1, 100}]]

I am using version 7, on windows XP SP2.

thanks
