AdvColumnGrid Row Highlighting

Hi,

 
Having upgraded TMS and now using Version 3.1.3.0 of TAdvColumnGrid control, when multi-selecting using Ctrl + Mouse click the colour of the latest row selected is different to the row or rows that are already selected.If Ctrl + A is used to select all rows then the last row is a different colour to the rest. All cells are read only.
 
This behaviour is different to a previous version of the control that we were using (3.1.2.3) which set all selected rows to the SelectionColor. Now, the last selected row is highlighted with the SelectionColor but the other rows become Green and there doesn't appear to be a property to change this Green colour.
 
Is this a deliberate change and if so, how do we revert to the previous behaviour?
 
Regards,
Matt
 

The color difference should only be minimal and this is a change by design to make the difference visible between the row that is selected and has focus and other rows that are selected but do not have focus.
