we have a very strange issue, on windows O.S all of our application DataGrid's middle columns look lighter (as if their alpha has been adjusted) then ones on the edges, we tested it on mac O.S and it seems fine there, we took out all styles but issue still exist, what is the setting that makes datagrid middle columns to look different that ones on the edge? is there even such a thing? this is url for screenshot : http://farm4.static.flickr.com/3198/2733290248_b33cb5c597_b.jpg
all help would be appreciated Kind Regards levan.
