Grids are rendered differently in upcoming versions of Google Chrome
From Chrome 18 upwards tables with table-layout:fixed are rendered differently. (Rightly or wrongly, I don't know)
This causes grids that are 'fit' to the width to spill over and some columns become inaccessible.
This problem is most evident in grid with many columns, because the border of each cell isnt being taken into account when calculating the width.
