I'm not able to duplicate this problem. Here's what I tried

CLOSE TABLES ALL
USE (HOME()+"SAMPLES\TASTRADE\DATA\CUSTOMER.DBF")
DELETE FILE EmptyColumnExample.sc?
CREATE FORM EmptyColumnExample NOWAIT
LOCAL laObj[1]
ASELOBJ('laObj',1)
WITH laObj[1]
  .ADDOBJECT('Grid','Grid')
  WITH .GRID
    .RECORDSOURCETYPE = 0
    .COLUMNCOUNT = 1
    WITH .COLUMNS(1)
      .REMOVEOBJECT('Text1')
    ENDWITH
  ENDWITH
  .ACTIVATE
ENDWITH
KEYBOARD '{CTRL-W}'
MODIFY FORM EmptyColumnExample

>You ask me why i use a column withou text control ?
>simple, because for a readonly grid it is fast a sure ( on VFP7 ) and simple to uses.

You don't have to tell me < g >. I do this myself occasionally.
