With, MBPM v9.0.1.1 the alignment of grid columns leaves something to be desired. In IE8, the total width of all the columns must be the width of the grid component less 4px otherwise the columns will start to get mis-aligned. If you leave the total width of columns 'short' to allow for a vertical scroll bar for instance, the columns no longer align with the column headings. If you fill the width of the grid a vertical scroll bar also causes a horizontal scroll bar (very annoying).
This behaviour does not happen in FireFox and columns align OK.
I know that I can paginate the grid but it is sometimes desirable to scroll a grid to provide a more speedy interface for the user.
